new genes are formed

cytoplasm is always exchanged

(can be more than one answer)

the zygote becomes haploid

Answer 1

The answer is a zygote is formed.

In the process called fertilization, the egg cells or so called ovum will fuse with a sperm cell. The result of this fusion leads to the development of the zygote which will then develop to an embryo.

Answer 2

Answer;

-zygote is formed

Once an egg has been fertilized zygote is formed.

Explanation;

-Fertilization is the fusion of two haploid gametes to produce a diploid zygote. Each haploid gamete in humans has 23 chromosomes, while the diploid zygote has 46.

-A fertilized egg is called a zygote until it divides into 16 cells, forming a ball-shaped structure called a morula. In humans, it takes about four days for a zygote to become a morula and another three days until the embryo attaches itself to the mother's uterine wall.
