Summary Introduction
To review:
The reproduction in Komodo dragon, the advantage of this type of reproduction, and the significance of the offspring produced, which were all males.
Introduction:
The Komodo dragon (Varanus komodoensis) is one of the largest living lizard, which is found in the islands of Indonesia. They are very large in size and can reproduce both sexually and asexually. Invertebrate animal species undergo asexual reproduction in order to rapidly increase their population as genetic clones of the parent are produced.

You find two closely related species of fly, one (P) of which appears to reproduce parthenogenetically while the other (S) reproduces sexually. In the same location, I find a third kind of insect, a sterile defensive form. Because it is sterile, I conclude this form must be produced by either P or S. Which do you think is most likely the producer of the sterile defensive individuals?
Using this information, how do I figure out the answer to question1?
INTRODUCTION
In most species of Drosophila, a female mating with a single male usually supplies sufficient sperm to fertilize her lifetime supply of eggs. Moreover, mating is often costly to female flies. So why do females of some species mate more than once? Perhaps they do this to assess the quality of males and/or the sperm males produce via sperm competition.
Tom Price, Nina Wedell, and their colleagues at the University of Exeter provide evidence for the sperm competition hypothesis. They show multiple mating increases in frequency when a selfish genetic element that reduces sperm quality is prevalent.
In Drosophila, females are XX and males are XY. They normally occur in equal numbers. In D. pseudoobscura, males that harbor the X-linked selfish genetic element sex ratio (SR) have produced nearly all female progeny, as SR sabotages Y-bearing sperm. The SR element gains a tremendous transmission advantage but…
In many hummingbird species in North America, males but not females have a bright red throat patch and both sexes show a preference for red-colored flowers over those with different colors. How would you determine that the sexual dimorphism in throat patch coloration in male hummingbirds evolved by sensory exploitation?

- Under what conditions should natural selection favor production of many offspring versus the production of a few well-provisioned offspring?arrow_forwardSome animals in captivity have reproduced without the need for a mate in a process called parthenogenesis. Examples include boas, pythons, bonnethead sharks, and komodo dragons. Initially, scientists thought this occurred because the animals were kept in optimal conditions for reproduction, but lacked access to a mate. However, scientists were surprised to discover that some species in the wild with access to mates also reproduce through parthenogenesis. An example is the pit-viper. Compare and contrast the processes of asexual reproduction through parthenogenesis and sexual reproduction for an animal such as the python. Describe the processes of i. asexual reproduction through parthenogenesis ii. sexual reproduction 2. Describe two pros and two cons of each form of reproduction. Explain each one.arrow_forwardotamopyrgus antipodarum is a species of freshwater snail that has spread far beyond its native New Zealand. Some populations of these tiny snails reproduce sexually, and other populations reproduce asexually. Huge asexual populations are now disrupting ecosystems all over the world, particularly where the water is contaminated with phosphorus. Fertilizers and detergents contain phosphorus, so agricultural runoff and other forms of water pollution are common in these regions. Like most animals that cannot reproduce sexually, the asexual snails have at least three sets of chromosomes; like most sexual organisms, the sexual snails have two. Explain why sexually reproducing snail populations predominate in regions where the water is unpolluted.arrow_forward
- Assume you are studying development in two species of iguana. You determine that a certain gene, "SPN2" turns on and off at different times in the two different species. The difference in timing leads to a different body length between the two iguana species. This phenomenon is an example of which of the following terms? a. Punctuated Equilibrium b. Pleiotropy c. Gene duplication d. Heterochronyarrow_forwardMany species can reproduce either asexually or sexually. Explain what you think might be the evolutionary significance of the switch from asexual to sexual reproduction that occurs in some organisms when the environment becomes unfavorable.arrow_forwardYou are raising a stock of Drosophila flies in which you have clipped off the wings of each individual. Assume that this treatment does not disrupt their mating success (it would). If you clip off the wings in each subsequent generation, what would you expect to observe in the 50th generation? Why? This is an example of whose ideas in evolution?arrow_forward
- Scientists studying reproduction compared three closely related species of bagworm moths. The reproductive methods for these species are given in the table. Which of the following research questions would provide additional information about the population level impacts of meiosis and sexual reproduction? A - How do the number of D. charlottae offspring compare with the number of S. rupicolella offspring? B - Do D. charlottae and S. rupicolella populations express greater genetic diversity than D. fennicella populations? C - Are the offspring of D. fennicella genetically unique compared to the offspring of D. charlottae and S. rupicolella? D - Does crossing-over in D. fennicella result in increased genetic variation compared to D. charlottae and S. rupicolella?arrow_forwardThe arctic fox has 50 chromosomes (25 per set), and the commonred fox has 38 chromosomes (19 per set). These species can interbreed to produce viable but infertile offspring. How many chromosomes would the offspring have? What problems do you think mayoccur during meiosis that would explain the offspring’s infertility?arrow_forwardA dairy farmer chooses to mate a male bull only with the female heifers that always make the greatest amount of milk, rather than heifers that produce a small amount of milk. What process is the dairy farmer employing when producing the next generation of calves?arrow_forward
- From an evolutionary standpoint, why is sexual reproduction advantageous for the continuation of a species?arrow_forwardApple maggot flies feed on the fruits of a specific host tree, and mating occurs on and near the fruits of these trees. Originally, apple maggot flies existed only on the fruits of hawthorn trees, which are native to North America. However, approximately 150 years ago, apple maggot flies were observed on cultivated apples, which are related to hawthorns but a different species. Today, many apple trees throughout North America are infested with the flies. These scientific findings reveal what appear to be the initial stages of what type of speciation in the apple maggot fly? a. Allopatric speciation b. Sympatric speciation c. Genetic diversion d. Microevolution e. Polyploidyarrow_forwardThe phenomenon of ____ results from the unequal size of the male and female gametes and the markedly different amounts of parental investment in the resulting offspring. As a result of this phenomenon, females tend to be the choosier sex in most vertebrate species. A. anisogamy B. isogamy C. isostacy D. pleiotropy E. heterogeneityarrow_forward
