Detailed explanation-1: -These cells are called gametes, but you might know them as sperm and egg. Each gamete contains half the number of chromosomes, or genetic material, of the organism. So, each sperm contains 50% of the father’s genes and each egg contains 50% of the mother’s genes.
Detailed explanation-2: -In asexual reproduction all the genes in the offspring come from one parent. In sexual reproduction one full set of the genes come from each parent. Living things produce offspring of the same species, but in many cases offspring are not identical with each other or with their parents.
Detailed explanation-3: -A sperm cell, with over 8 million chromosome combinations, fertilizes an egg cell, which also has over 8 million chromosome combinations. That is over 64 trillion unique combinations, not counting the unique combinations produced by crossing-over.
