Question

Why are there two copies of each chromosome? Question 5 options: One copy comes from each parent Chromosomes were duplicated in mitosis The chromosomes copied themselves through DNA replication

Answer 1

One copy comes from each parent

Step-by-step explanation:

The correct answer would be that one copy comes from each parent.

During gamete formation, the chromosome number in the sex cells is usually halved to produce haploid gametes. Haploid gametes fuse together and donate their chromosomes to form a diploid zygote during the fertilization process. Hence, one copy of the two chromosomes in diploid organisms comes from each parent.
