Answer:
Through formation of zygote by using gene pool of two gametes
Explanation:
During fertilization, an offspring is produced from the gametes of parents. Due to independent assortment and recombination, each gamete has unique combination of gene because of the meiosis cell division. This leads to reshuffling of genes of the mating parents and thus causes genetic variation in a given population. This is the reason why offspring of the same parents differ from each other phenotypically. A zygote is formed when the gamete of the two mating parents combine.
Fertilization is the process of combining two gametes to form a zygote. The gametes fertilize to produce different phenotypic characters in the offspring.
Recombination:
It is a process of creating a new combination of genes in the gametes. During the miosis (I) the non-sister chromatids of homologous chromosomes exchange the genetic material. This results in the different genetic combinations in each gamete.
A gamete fertilizes to form a zygote and develop into offspring. The offspring will produce different traits according to the genes they have.
Therefore, gametes fertilize to produce different phenotypic characters in the offspring.
