The process of meiosis occurs during the cell cycle production and results in four unique diploidfour identical diploid cells four unique haploid cells four identical haploid cells . To maintain the correct number of chromosomes in offspring, male and female gametes contain the same number half of the number twice the number of chromosomes as somatic cells. During fertilization, gametes fuse to form a diploid haplid cell called a zygote. Sexual Reproduction and Genetic VariationGenetic variation describes the genetic differences in DNA segments of organisms within a population. Genetic variation is important because it enables some individuals to have traits that arefavorable in a changing environment. Sexual reproduction is a method that introduces genetic variation.A human being is a diploid organism whose somatic cells contain 46 chromosomes found in 23 homologous pairs. Sexual reproduction requires that sex cells, or gametes, reduce their number ofchromosomes in order for fertilization to occur. In humans, meiosis is the process that forms the gametes required for reproduction.

Use the following information as the basis for answering the question: A diploid eukaryotic organism has 4 unique chromosomes. Chromosome I is metacentric, chromosome II is telocentric, chromosome III is submetacentric, and chromosome IV is acrocentric. 1. Draw the chromosomes (just the chromosomes, not a cell...) described above as they would appear in a cell in G1 AND in G2, and label each chromosome (I, II, III, or IV) and label all parts (centromeres and telomeres) of one of the chromosomes. Use the letter p to indicate a paternal chromosome and m to indicate a maternal chromosome
Which one of the following entries describes the relationship between sister chromatids? Contain the same genes, but may be different alleles Contain identical alleles of the same genes Inherit one homologous chromosome from mother, inherit one homologous chromosome from father. Very similar at the DNA sequence level
Global warming is an issue affecting many species around the world. Warming has caused the temperatures in lakes and rivers to increase and stay elevated for longer periods of time. Select the FOUR numbers that describe the possible effects of global warming on the reproduction of rainbow trout in the wild and on biodiversity. The extra set of chromosomes remains. The extra set of chromosomes is removed. The offspring are diploid (2n). The offspring are triploid (3n). The offspring cannot reproduce. The offspring can reproduce. Biodiversity decreases. Biodiversity increases. Please record the FOUR numbers in ascending order.
Human sperm or egg cells contain one set of chromosomes which is a configuration known as __________ or ________. Group of answer choices diploid, n diploid, 2n haploid, 2n haploid, n
Which of the following is true regarding where mitosis and meiosis occur within multicellular organisms? Meiosis occurs only in gamete-forming cells; all cells can perform mitosis. Meiosis occurs only in gamete-forming cells; mitosis is only for specialized dividing cells. Mitosis occurs only in gamete-forming cells; all cells can perform meiosis. Mitosis occurs only in gamete-forming cells; meiosis is only for specialized dividing cells.
Explain why the following statement is false: Sexual reproduction is the only mechanism for genetic change.
A human protein, MC1R is responsible for telling human cells what type of pigment proteins to produce. One version of MC1R causes cells to make red pigments, while another version causes our cells to make black pigments. The red version causes red hair. The black version causes black hair. The two versions are called ____? Group of answer choices 1. homozygous and heterozygous 2. homologous chromosomes 3. alleles 4. sister chromatids
The continuity of life is based on heritable information in the form of DNA. In a short essay (100–150 words), explain how chromosome behavior during sexual reproduction in animals ensures perpetuation of parental traits in offspring and, at the same time, genetic variation among offspring.
Most eukaryotic organisms use sexual reproduction as their primary means of perpetuating their species. Gametes are formed via meiosis. However, some species primarily reproduce via asexual means. Reproduction is accomplished via mitosis. Aspen trees most commonly reproduce by such asexual methods of cloning.What are the advantages and disadvantages of reproduction by asexual means? Why do some species reproduce in this manner? Why don't all species?
Considering both asexual and sexual reproduction, does the following statement apply to mitosis only, meiosis only, or both mitosis and meiosis? Mutations that occur during this process would ALWAYS be passed on to the next generation Neither mitosis nor meiosis Both mitosis and meiosis Meiosis only Mitosis only
The following four questions refer to the picture below: 1) In meiosis, the homologous chromosomes are side by side. Are they side by side in mitosis? 2)In meiosis, each centromere has a spindle fiber attached only to one side. In mitosis, each centromere has a spindle attached to how many sides? 3) Look at what happened right after Metaphase in both processes. In mitosis, what has been separated homologous chromosomes or sister chromatids? 4) After Metaphase I in meiosis, what has been separated, homologous chromosomes or sister chromatids?
