Concept 10: Gene Segregation in Mitosis

Mitosis maintains a constant amount of genetic material from cell generation to cell generation.

Consider a hypothetical diploid cell with one chromosome. Consider also that this cell is Aa; that is, it is heterozygous for a pair of alleles with A coming from one parent and a from the other parent.

In the figure below, notice how we start and end with cells having the same genotype.
