Answer :
Processes that provide perpetuation of parental traits and genetic variation among offspring are Independent assortment of chromosomes, Crossing over, and random fertilization.
Heritable information DNA is the key idea of continuity of generation along with variation in progeny. Independent assortment is Mendel's law states that alleles of two different genes get sorted into gametes independently of one another. In this process where the chromosomes move randomly to separate poles during meiosis.
Crossing over is the exchange of genetic material between two non-sister chromatids of homologous chromosomes resulting in new allelic combinations. It increases the variability of the population and prevents the accumulation of deleterious combinations of alleles, while also allowing some parental combinations to be passed onto offspring.
