A gamete is a reproductive cell that merges during sexual activity. A male cell called sperm unites with a female cell, referred to as the egg or ova. During reproduction, it becomes a zygote, which is the marriage between male and female gametes. A gamete is created by cell division, and this procedure is called meiosis.
Upon sexual activity, once the male and female gamete become a zygote, the haploid would come to be a diploid. A diploid involves having two sets of chromosomes. It is the gamete that determines the gender of a person. It is comprised of the sperm and egg.
On the other hand, a genotype is the genetic makeup of the cell, and it is different for everyone, even if babies are identical twins. A genotype is more of the organisms' genetic makeup, while genotype is the physical expression of genes.
Chromosomes are conveyed in pairs of letters, called alleles. A genotype is comprised of chromosomes, genes, DNA, and alleles. Genotype determines things like hair, color and texture, and eye color. Genotype can even have a considerable effect on someone's personality. Each gamete carries half a genotype, and the result is diploid.
