WebSep 4, 2024 · Genes in Populations. Individuals do not evolve because their genes do not change over time. Instead, evolution occurs at the level of the population. A population consists of organisms of the same species that live in the same area. In terms of evolution, the population is assumed to be a relatively closed group. WebSince all cells in our body contain DNA, there are lots of places for mutations to occur; however, not all mutations matter for evolution. Somatic mutations occur in non-reproductive cells and so won’t be passed on to offspring. For example, the yellow color on half of a petal on this red tulip was caused by a somatic.
WebNov 10, 2024 · Genetic variations create diversity within a species. Changes in environmental factors such as habitat loss, increased pollution, climate change, and invasive species can challenge the survival of members of a population. Organisms that survive pass their traits on to offspring. WebOne simple way of measuring the variability of a gene locus is to ascertain what proportion …
