The product of the union of sperm and egg is a(n) ____
A
embryo
B
gametophyte
C
fruit
D
zygote
Explanation: 

Detailed explanation-1: -zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

Detailed explanation-2: -The fusion of sperm and ovum (egg cell) is called fertilization. Fertilization results in the formation of a diploid zygote with single nuclei from which a new individual develops.

Detailed explanation-3: -Hence, a Zygote is diploid. Each chromosome is present in two homologous, or comparable, copies in almost all human body cells. Due to the presence of both of its parents’ genes, the zygote is diploid (carrying two sets of chromosomes).
