Question

Answer 2

Answer:

The amount of DNA remains the same during sexual reproduction because of the fusion of gametes.

Explanation:

The amount of DNA remains the same during sexual reproduction because:

• In organisms undergoing sexual reproduction, the total amount chromosomes are given by 2n.
• All the genes contain 2n chromosomes, however, gametes only contain n chromosomes.
• During sexual reproduction gametes from the male and female parent combines to form a zygote. Since the zygote is formed due to fusion it contains the '2n' chromosome.
