Asexual reproduction is a style of reproduction which offspring are formed by a single organism, and inherit the genes of one parent only; unlike sexual reproduction, which requires the genes from two parent organisms in order to create an offspring, asexual reproduction occurs when a single organism. This causes the offspring to almost a duplicate of the one parent it inherits its genes from. Asexual reproduction is done externally and it commonly used by sea creatures like seahorses, Parthenogenesis, Copperheads, coral, sea anemones and starfish. It is also used in some plants like for example strawberries, potatoes and onions. And it is used by decomposers like fungi and bacteria. Asexual reproduction is common among living things and takes a variety of forms.
Vegetative propagation Description Examples
Lignotuber A starchy, woody swelling of the root crown which some plants have adapted it provides protection against destruction of the plant stem, such as by fire, it also serves to help contain water for very dry conditions. The crown contains buds from where new stems sprout from, it also acts as a container which stores of starch, that can support a period of growth in the absence of photosynthesis. It is found commonly in Australian flora, in resilience to the high possibility of bush fires that occur annually and the high humidity and heat rates. In Australia this feature is found in the eucalyptus tree, marginata(Jarrah), most mallees, and many Banksia species.

We basically said that the bird’s mate has to have the same genes and traits but the mate doesn’t show the mate so I’m assuming that the bird was asexual in the first place. The lab is basically telling us that the bird reproduced by itself but I don’t think that’s how birds work. Overall, I think the lab isn’t that realistic unless if the bird is asexual.
Asexual Propagation is the process of using plant materials such as the stems, leaves, and roots to multiply the number of plants. These plants eventually grow to be a brand new plant that is genetically identical to the parent plant it came from. In several types of plants, asexual propagation is the fastest means of new plant growth. Asexual propagation is also a good way to maintain a plant species because they are genetically identical. In this process, adventitious roots are seen in the growing cycle. Adventitious roots are those that grow form parts of the plant that they normally would not grow from. The cuttings must do
Budding is a type of Asexual Reproduction, when the parental body grows reproductive units on its body, called buds. The buds will eventually grow into a full size organism. In the process of developing, the bud may be separated from the parental cell when growing, or may be separated only after it grows to full size.
D) Sexual reproduction is more likely to increase genetic variation than is asexual reproduction. E) Only asexual
The River Red gum has prevailed to this by allowing its seeds to be taken to higher ground and distributed. Seeds of the River Red gums (see image 7) have spongy tissue with air spaces (Aerenchyma) that allow it lose water. This is handy when the seed is immersed in water during the flooding season.
Stems are long and weak, square in cross section, prickly (spiny) with glands on young parts. Leaves are matt, mid-green, deeply veined and sometimes hairy. The lamina is pear or oval shaped, pointed to broadly-rounded apex, rounded base, round or regular toothed margins with wrinkled and strigose (sharp oppressed rigid bristly hairs) upper surface. When the leaves are crushed, a strong and distinctive odour is exuded. Flower heads have many smaller flowers. Each flower is tubular-shaped and have 4 spreading lobes (petals), changing colour with age. The colours would be a various combinations of white, yellow, orange, red or pink. Fruit is a berry or drupe arranged in clusters. The fruit is green and becomes purple-black when mature. This plant takes over huge areas usually in moist gullies, along drainage lines and around wetlands. It can be found scrambling high into tree tops. The intense growth of the weed restricts any plant to grow beneath it or around it. This results in plant growth being restricted and not allowing plantation to develop.
There are many methods of reproduction, but the two main methods are sexual and asexual, but which one is more efficient or beneficial. Sexual reproduction is the fusing of two gametes to produce an offspring. This form of reproduction is used by a lot of organisms, including us. Asexual reproduction is reproduction that only involves one parent. (“Pros and cons of sexual and asexual reproduction”). I am going to focus on asexual reproduction and the Desert Grassland Whiptail Lizard. This unique lizard uses asexual reproduction. Asexual reproduction is better for this species of lizards because it only requires one parent, it is less risky, and the population is only female.
Despite all this, the question keeps coming back; why is sexual reproduction still the choice of reproduction or even exist? Why can’t all species reproduce asexually?
Asexual reproduction is one parent reproducing an offspring that are genetically alike. The purpose of asexual reproduction is so that the reproductive process can go faster without any mistakes. Sexual reproduction is a combination of genetics from the patents to reproduce an offspring. The purpose of sexual reproduction is so that evolution can take place from the organism. The animal focus today is the desert grassland whiptail. The whiptail tail uses asexual reproduction. This whiptail uses the more beneficial reproduction because fertilization is not needed, so only one parent is involved. Also, their is a high chance that the offspring would be created successfully.
Without reproduction a species would become extinct. There are two types of ways to reproduce. Sexual reproduction is when two parent organisms come together and combine genetic information to give birth to an offspring. Examples of sexual reproductions include human beings, animals, and insects. Asexual reproduction is when an organism can reproduce with only one parent such as starfish and bacterium. Viruses can multiply but they cannot do so on their own. Viruses because viruses are not cells, they can replicate only by invading a host cell and using the enzymes and organelles of the host cell to duplicate. Replication can occur by either the lytic or lysogenic cycle. Viruses are part of an extraordinary life cycle. If a virus infects a cell for a long period of time they are in a lysogenic cycle. During a Lytic cycle, the viral genome is released into the host cell and replication of the virus follows immediately. A virus does not contain the right cell parts to reproduce which causes a virus to go and infect a cell to
In Generation 3, we can see there is different pairs of color dot in the sexual experiment which produced different color dots than the original one. For example, the same 2 color dot can produce different color offspring, as the chart above, two lime produces 2 cream 4 lime and 2 brown. In Asexual chart, the color of parent can only reproduce 1 type of offspring, because they reproduce as single, and there is no diversity in each individual. Thus, Sexual reproduction has more diversity than Asexual reproduction. Asexual reproduce from single parent, there is no way to reproduce variation, they are the individuals that have to same DNA from their parent, their traits are the same automatically. In other hands, There are 2 parents reproduce offspring in Sexual reproduction. Their offspring is combine with the sperm and egg from the parents, and the sperm and egg include different chromosomes which has two different traits from the male parents and the female parents, then the offspring include some traits from the male parents and some from the female. Over time, the offspring
Sea stars can reproduce sexually and asexually. In sexual reproduction, fertilization occurs in the water with males and females releasing sperm and eggs into the environment. The fertilized embryos, which are free-swimming animals, become part of the zooplankton in most species. If they break in half they can produce another Sea Star, which relates to regeneration.

ANIMAL REPRODUCTION & DEVELOPMENT Dr Ilma • The two earthworms in this picture are mating • Each worm produces both sperm and eggs, which will fertilize – And in a few weeks, new worms will hatch Asexual And Sexual Reproduction • Both occur in the animal kingdom • Asexual reproduction is the creation of new individuals – Whose genes all come from one parent • Sexual reproduction is the creation of offspring – By the fusion of male and female gametes to form a zygote Mechanisms of Asexual Reproduction
A bacterium can reproduce by dividing itself into two within 20 minutes; a vine branch cut into ten segments can plant ten grapevine; a strawberry plant can produce hundreds of strains within a year by crawling along its stolon. In nature, some plants and single-celled organisms produce genetically identical posterity through a process called asexual reproduction. In asexual reproduction, a new individual is generated from a copy of a single cell from the parent organism, which can also be called “clone” . At early stage, Theodore Puck stated that “A clone is a population of cells, all of whose members are descendants from the same single organism” . While with the development of time, the term “clone” has been defined more broadly. It can be described as the process used to create an exact copy of a mammal by using the complete genetic material of a regular body cell, or organisms that are exact genetic copies. Cloning technique has
