Question
1. One sister chromatid of a chromosome has the allele H. What allele will the other sister chromatid have assuming no crossing over? 2. Two alleles on one homologous chromosome are "A" and "B." The other homologous chromosome's alleles are "a" and "b." How many different genetic types of gamctes would be produced without crossing over? (Refer to the left side Figure 3) a. b. What are those types? e. I occur, how many different genctic types of gametes would be produced? (Refer crossing over were to to the right side of Figure 3) d. List them. 3. Compare and contrast mitosis and meiosis. 4. From a genetic standpoint, what is the significance of fertilization? 5. How do interkinesis and interphase differ? Of what significance is the difference?Explanation / Answer
1. When the cell is in resting phase or non division phase, the chromosome contains only one DNA molelcules. When the cell underoges the division, after S phase (where the DNA duplication occurs) they will get another dna strand (replica of one DNA). As it is the replica of parental DNA the another sister chromatid also contains the same allele i.e. H.
