The egg enyrecruzamiento may be produced either by meiosis or mitosis. Explain the causes of genetic recombination, particularly the inheritance of linked traits and results of crossing over during meiosis. Retrieved from ” https: So, the parthenogenetic greenfly offspring are not identical, and do show some genetic variation: As with shuffling a deck of cards, many different combinations of genes can be produced without a change mutation in any individual gene.

The offspring gets a set of chromosomes from each parent so that, overall, half of its heredity comes from each parent. Although the gametes have only one set of chromosomes, that set is a shuffled mixture of genetic material from both parents.
