In a general view of all species whom reproduce sexually, a single HAPLOID gamete from each parent fuse in fertilization to form a zygote. Haploid means it is a single set of genes (of independent assortment) as opposed to standard body cells which are diploid. Through the process of meiosis, 4 distinct and unique gametes (caused by interdependent assortment of parental DNA and the process of synapsis) are produced for every cell which undergoes the process; in males this number is extremely high while in females fewer gametes are viable or created. This being said, an offspring inherits 50% of its genome from each parent, however each parent produces genes coding for the same features. Alleles of the same gene, whether dominant or recessive, are responsible for phenotypic traits expressed in the offspring.
