Question

the incremental changes weve considered in the canid colony are the building blocks of evolution. speciation can occur in many different ways. what is the difference between genetic drift and natural selection? click the view theory button if you need guidance to answer the question. a) genetic drift influences evolution through random chance. evolution by natural selection results in better environmentally adapted populations b) genetic drift relies on constant new mutations whereas mutations do not influence natural selection c) genetic drift means the best - adapted organisms survive. natural selection is used by breeders to produce better - adapted groups or organisms

Explanation:

Genetic drift is a random - change process in allele frequencies in a population. Natural selection is a non - random process where organisms better adapted to the environment survive and reproduce more successfully. Option a correctly describes this difference. Option b is wrong as mutations influence both genetic drift and natural selection. Option c misdefines genetic drift (best - adapted survival is natural selection) and misrepresents natural selection (it's a natural process, not something breeders use in the way described).

Answer:

A. Genetic drift influences evolution through random chance. Evolution by natural selection results in better environmentally adapted populations
