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.

If your body lacks enzymes that break down
carbohydrates, it would be unable to get sugar molecules for energy production.
If you lacked the enzyme to digest proteins, you may not absorb enough amino

The digestive system in our body changes
carbohydrates into glucose; also known as blood sugar to be use as an important
source of energy. Meanwhile, amino acids are organic compounds that combine to
form proteins, which are the building blocks of life.
