Homework Answers
Metaphase-I is characterized by the alignment of chromosomes on the equatorial plane. Each chromosome contains two sister chromatids and is bound by spindle fibers from only one end.
Anaphase-I: Homologous chromosomes are separated.
Anaphase-II: Sister chromatids are separated
Telophase-II: Four haploid daughter cells are produced

3. The mosquito that causes Yellow fever has 6 chromosomes (2n = 6). a. Accurately draw and label a cell of these mosquitos in each of the 4 phases of mitosis (Prophases, Metaphase, Anaphase and Telophase). Be sure to include (and label) in your drawings the chromosomes and spindle fibers. b. Accurately draw and label a cell of these mosquitos in each of the following 8 phases of meiosis: Prophases 1, Metaphase 1, Anaphase 1, Telophase1, Prophases 2, Metaphase 2,...

Simulate meiosis by drawing Two pairs of chromosomes with crossing over Assume that two of the genes are on chromosome 1, and one of the genes is on chromosome 2. Allow crossing over to occur between the two genes on the same chromosome. Also, are there multiple ways that the chromosomes could segregate to produce different results? Show them. Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 2 pairs of...

1. Draw TWO PAIRS of metacentric homologous chromosomes as they would appear, if they could be seen, during of the cell cycle. Indicate centromeres with a small circle. For one pair of homologs, place the allele on one chromosome and the allele a on the other chromosome. For the other pair of homologs place the allele on one chromosome and the alleleb on the other chromosome. 2. Draw the same chromosomes as they would appear at the end of prophase...

3) The diploid cells of A. roksiki have a total of 4 chromosomes (2n=4). One of the homologous pairs is large with an acrocentric centromere and the other is small with a metacentric centromere. A. Draw the chromosomes from A. roksiki as they would appear in metaphase 2 of meiosis. Include all cells and all chromosomes. Assume meiosis is proceeding normally and ignore any effects of crossing over. (6 pts) B. A strain of A. roksiki is heterozygous for a...

5. (16 pts.) A cell has two pairs of submetacentric chromosomes, which we wili cail chromosomes I,, Ib, Ila, and Ilb. Submetacentric chromosomes have their centro nere abou midway between the telomere and middle of the chromosome as shown. Chromosomes Ia and I, are homologues and chromosomes II, and Ilb are homologues. Allele R is located on the p arm (short arm) of chromosome of chromosome la, and allele r is located at the same position on chromosome lb. Allele...

Generating. A cell is 2n = 4 and will soon go through meiosis I and meiosis II, to become four genetically distinct haploid cells. Draw and label all the stages (prophase I, metaphase II, etc.) and the location/distribution of chromosomes using red and blue colors for the chromosomes in cach stage. In at least one of the homologous pairs, show crossing over using two different alleles of your choice. (15 points)
