Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy …
WebSee Answer. Question: Mark the statements that are true of Mendel's Law of Segregation. Each parent provides one copy of each chromosome. There is only one version of each gene. Each gamete contains identical alleles. Each gamete carries one version of each. Mark the statements that are true of Mendel's Law of Segregation. WebDescribe the anatomy of a human sperm and a human egg. As a part of your answer, explain what each gamete contributes when making an embryo, and how their respective forms and development dictate their relative functions. Explain oogenesis and how this leads up to meiosis. What hormone(s) do ovaries produce?
WebFertilization. Fertilization creates genetic diversity by allowing each parent to randomly contribute a unique set of genes to a zygote. While fertilization is not part of meiosis, it depends on meiosis creating haploid gametes. The fertilized cell restores the diploid number. Without meiosis, the number of chromosomes per cell would double in ...

WebThe gametes produced in meiosis aren’t genetically identical to the starting cell, and they also aren’t identical to one another. As an example, consider the meiosis II diagram below, which shows the end products of meiosis for a simple cell with a diploid number of 2n = 4 chromosomes. The four gametes produced at the end of meiosis II are all slightly …
WebEach gamete receives both of the parent's alleles for the each gene. Alleles segregate into different gametes with equal frequency. Allele frequencies (i.e., proportions) in gametes cannot be predicted in advance. Dominant alleles segregate into gametes more frequently than recessive alleles.
