WebGenetic variation is the raw material of evolution. Without genetic variation, a population cannot evolve in response to changing environmental variables and, as a result, may face an increased risk of extinction. For example, if a population is exposed to a new disease, selection will act on genes for resistance to the disease if they exist WebDec 9, 2024 · When a species has a lot of differences in its DNA, we say that genetic diversity is high [ 2 ]. In species with high genetic diversity, there are lots of mutations in the DNA, which cause differences in the way individuals look as well as differences in important traits that we cannot see [ 2 ]. This is called adaptation.

Differential gene expression between species and sexes. WebGenetic Diversity. Species are populations of individuals that can and do reproduce together. The differences between individuals in a population are more than just skin deep -- they differ in their genes. Genetic variation among individuals in a population is what ensures that the species will be able to survive in a changing environment. WebThis diversity of possible gametes reflects two factors: crossing over and the random orientation of homologue pairs during metaphase of meiosis I. Crossing over. The points where homologues cross over and exchange genetic material are chosen more or less at random, and they will be different in each cell that goes through meiosis. can a three year old take zofran
