While examining the mitotic stage in a tissue, one finds some cells with 16 chromosomes and some with 32 chromosomes. What possible reasons could you assign to this difference in chromosome number? Do you think cells with 16 chromosomes could have arisen from cells with 32 chromosomes or vice versa?

Answers (1)

The difference in the chromosome numbers can be attributed to Mosaicism. It is the phenomenon that describes the existence of two types of chromosome numbers in a different cell of the body. This situation arises due to lag of anaphase or non-disjunction of chromosomes.
