Answer:
The correct option is B: 2
Explanation:
Before meiosis takes place, the entire genetic material within the cell is replicated, this results in 2 copies of the 2n DNA. Since the person is heterozygous for the mutated allele, there is one copy of it present within one 2n set of chromosomes. Two of the 2n chromosomal sets means there would be two copies of it present in total and when the segregation event happens to create haploid cells, two of the cells will inherit the mutated copy.
