In most sexually reproducing organisms, the diploid phase of the life cycle begins at
valkas [14]

The diploid phase of the life cycle begins with the formation of the zygote.

Meiosis is referred to the type of cell division which occurs in the production

of male and female sex cells. This also occurs during sexual reproduction.

Parent cells provide male and sex cells such as sperm and egg which

contains DNA. They then fuse together to form a zygote which is the diploid

continues to undergo some meiotic processes which reduces it to back to a

haploid cell and consequent growth to form a fetus.
