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.
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.
