The bulldog ant has a diploid chromosome number of two. Therefore, at the end of meiosis I, each daughter cell will have a single chromosome. There is/are _____ possible combination(s) of genes in the daughter cells of meiosis II because _____.   A. none of the above because the species is polyploidy   B. Only 1; there was only one chromosome per daughter cell after meiosis I   C. More than 2; the non-sister chromatids of the two homologues crossed over prior to metaphase I   D. 2 ; because there were two homologous chromosomes per cell at the beginning of meiosis I

Below is a chromosome with arrows showing the breakpoints of an inversion. ABCDE F.GH 券 What would be the products of meiosis if a chromosome carrying the inversion paired with a wildtype chromosome and crossover occurred between the interval C and D? (Indicate which products would be viable and which would be lethal and why,

and down syndrome the victim has an extra chromosome 21. Therefore, down syndrome is a kind of ___ and results from ___. A. aneuploidy... nondisjunction of chromosome 21 during meiosis B. polyploidy... occurrence of meiosis without cytokinesis C. translocation… insertion of a transposon into chromosome 21 D. replication air… An extra cycle of DNA synthesis during the five phase

Is this the correct option?

Which of the following statements are true regarding homologous pairs of chromosomes? Select all that apply. A. They are the same size B. Their prescence indicates a cell is a diploid C. They are identical copies of one another D. One of the homologous chromosomes in a set is synthesized during S phase E. They line up next to each other during metaphase I of meiosis F. They are separated in anaphase I of meiosis

2. An organism is 2n=4 with genotype AaBbEe. Genes A and B are close together on the larger chromosome, and gene E is on the smaller chromosome. a. Using a vertical metaphase plate, draw the two independent orientations of this AaBbEe cell in Metaphase I of Meiosis. b. Label alleles on all chromatids. c. Write the alleles in each possible gamete on the lines below each orientation. OR O'Q ( Gametes:

The major way that meiosis II differs from mitosis is that O A. in meiosis II, the homologous sister chromatids align at the metaphase plate as a tetrad. in meiosis II, the cells are haploid. В. in meiosis II, a pair of sister chromatids move to the pole. in meiosis II, the homologues separate. D.
