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.
These vegan-like diets eliminate all animal products, including meat, poultry, fish, eggs, dairy and honey. Everything you eat â including whole grains, fruits, vegetables, legumes, nuts and seeds â is derived from plants. Research reflects that following a plant-based diet has health benefits, if you do it correctly. A plant-based diet is also more likely to result in weight loss than a vegan diet.
