Chiasma (genetics) In genetics, a chiasma (pl. chiasmata) is the point of contact, the physical link, between two (non-sister) chromatids belonging to homologous chromosomes. At a given chiasma, an exchange of genetic material can occur between both chromatids, what is called a chromosomal crossover, but this is much more frequent during meiosis than mitosis. In meiosis, absence of a chiasma usually result in improper chromosomal segregation and aneuploidy.
For example, certain kinds of breast cancers are insulin sensitive, and thus eating a lot of carbohydrates (ironically like in a vegan diet) would cause your body to produce lots of insulin, making this an inefficacious strategy in reducing risk for those particular kinds of cancer.
Fruits and vegetables are staples of the vegan diet. As many omnivores or meat eaters would guess, fruits and vegetables are staples of the vegan diet. Vegans eat them in salads, casseroles, stir fry dishes and with dips such as hummus and baba ghannouj. All vegetables and fruits are considered vegan in their natural, raw states.
