Solutions For An Introduction to Genetic Analysis Chapter 3 Problem 13P

Step-by-Step Solution

Solution 1

Mitosis is a process where the parent cell duplicates and divides into two daughter cells. The absence of variation in daughter cells produced is due to the absence of the process of cross-over. When normal mitosis takes place in a diploid cell of the genotype A/a; B/b, the possible daughter cells will have the same genotype as the parent mother cell.

Picture 1

Hence out of the following genotypes:

a. A ;B

b. a ; b

c. A ; b

d. a ; B

e. A/A ; B/B

f. A/a ; B/b

g. a/a ; b/b

The correct answer would be (f) A/a; B/b, since daughter cells produced in mitosis are fully identical to the mother cell.
