They retain half of their chromosomes.
|
|
half of the cells copy their DNA twice.
|
|
their nuclei fuse to from one nucleus.
|
|
one becomes an egg, and one becomes a sperm cell.

Detailed explanation-1: -Through fertilization, the egg and sperm are saved: the egg is activated to begin its developmental program, and the haploid nuclei of the two gametes come together to form the genome of a new diploid organism.
Detailed explanation-2: -If a sperm cell fertilizes an egg cell, the nuclei of the two cells combine. A new cell with a complete set of genetic information is produced – one half is from the mother, and the other half is from the father. The fertilized egg cell can now start developing into a baby.
Detailed explanation-3: -The process in which the male sex cell fuses with the female sex cell is called fertilisation.
Detailed explanation-4: -fertilization, union of a sperm nucleus, of paternal origin, with an egg nucleus, of maternal origin, to form the primary nucleus of an embryo.
Detailed explanation-5: -Fertilization is a multistep process that culminates in the fusion of sperm and egg, thus marking the beginning of a new organism in sexually reproducing species.
