A drawing of a cell in G2 interphase is provided. The cell contains 4 replicated chromosomes with alleles (H, h, F, f) properly labeled. A set of sister chromotids is labeled.

A drawing of a cell in anaphase is provided. The cell contains 8 unreplicated chromosomes with alleles (H, h, F, f) properly labeled. The chromosomes are shown separating from each other with 4 chromosomes moving toward each side of the cell. Spindle fibers are labeled.

A somatic cell has the genotype DdEe. All chromosomes in this organism are metacentric. Show metaphase and the results of mitosis if the D and E locus are linked on the same chromosome in trans configuration. A sexually reproducing organism has the following phenotype DdEeAaTt: The D and E loci are on the same arm of a metacentric chromosome in cis configuration. The A locus is on the long arm of an acrocentric chromosome and the T locus is on a telocentric chromosome. 2.1. What is the haploid number of this organism? 2.2. Using diagrams show a ceii at metaphase of mitosis and show the results of mitosis.

consider a diploid cell that contains three pairs of chromosomes designated AA, BB, and CC. Each pair contains a maternal and a paternal member (e.g., Am and Ap, etc.). Using these designations, demonstrate your understanding of mitosis and meiosis by drawing chromatid combinations as requested. Be sure to indicate when chromatids are paired as a result of replication and/or synapsis. You may wish to use a large piece of brown manila wrapping paper or a large cut-up paper bag and work with another student as you deal with these problems. Such cooperative learning may be a useful approach as you solve problems throughout the text. Draw all possible combinations of chromatids during anaphase II in meiosis.
