WebHow does genetic variation occur in meiosis? There are three ways that the cells produced in meiosis are different from each other and from the parent cells:1) Independent assortment: this is the idea that during metaphase 1 and 2 pairs of homologous chromosomes randomly line up. WebMeiosis (/ m aɪ ˈ oʊ s ɪ s / (); from Ancient Greek μείωσις (meíōsis) 'lessening', since it is a reductional division) is a special type of cell division of germ cells in sexually-reproducing … chucked definition

Later, as two gametes combine during fertilization, this variation is increased even more, thereby producing offspring with special DNA combinations. WebMeiosis I results in an independent assortment of genes due to the random positioning of pairs of homologous chromosomes. As a result of the independent assortment, the meiosis process causes genetic variation. As a result, there are four primary forms of meiosis that result in genetic variation. chuck eddie\u0027s southington
