Question

How much DNA is located in an egg cell BEFORE fertilization?

a.) 100 percent (all of it)

b.) 50 percent (half of the DNA)

c.) none of it

Answer 1

B

Step-by-step explanation:

Gametes are haploid that contains 1 set of chromosomes.

To form a zygote, fertilisation occurs which causes the fusion of a sperm and an egg to form a diploid cell.

In each gamete, they contain 50 percent of the genetic material as compared to the zygote, fusing to form a zygote with 100 percent DNA after fertilisation.
