WebMeiosis I. The diagram below shows how nondisjunction can take place during meiosis I if homologous chromosomes don't separate, and how this can lead to the production of aneuploid gametes (eggs or sperm): Meiosis II. Nondisjunction can also happen in meiosis II, with sister chromatids (instead of homologous chromosomes) failing to separate. WebAs illustrated in the diagram below, the homologues of each pair separate in the first stage of meiosis. In this process, which side the "dad" and "mom" chromosomes of each pair go to is random. When we are following two genes, this results in four types of gametes that are produced with equal frequency.

WebThe difference between anaphase of mitosis and anaphase I of meiosis is that A. chromatids do not separate at the centromere in anaphase I B. Chromosomesdo not exist in anaphase I C. the chromosomes line up at the equator in anaphase I D. crossing occurs only in anaphase of mitosis half the number of chromosomes than its somatic cells WebThe gametes produced in meiosis are all haploid, but they're not genetically identical. For example, take a look the meiosis II diagram above, which shows the products of meiosis for a cell with 2n = 4 2n = 4 … churchill 2011

WebMetaphase I. Spindle fibers attach the chromosome pairs and move them to line up on a line known as the metaphase plate. Anaphase I. The cell elongates as the homologous … WebIdentify the stages of meiosis on the diagram. What happens during telophase II of meiosis? The nuclear membrane begins to form around haploid sets of chromosomes. What happens during anaphase II of meiosis? Sister chromatids separate from each other and migrate to opposite ends of the cell. What happens during prophase I of meiosis? WebDraw a diagram to show how nondisjunction of all chromosomes during meiosis I in one parent could lead to polyploid offspring. (Use 2n = 6 for the starting cells; assume the other parent’s gamete contributes the normal number of chromosomes.) Expert Solution Want to see the full answer?
