how is sex determined after meiosis
Introduction. Meiosis, the form of cell division unique to egg and sperm production, sets the stage for sex determination by creating sperm that carry either an X or a Y sex chromosome.his means that when the chromosomes of egg and sperm cells combine at fertilization, the embryo regains the normal diploid number. Meiosis mixes up the parental genes in two ways. First, the members of each chromosome pair come together and swap segments in a process known as crossing over, or recombination.
