Question

CLASS 10 who doesn't know f**I of
biology: heredity and evolution

what is genetic drift? {2 marks}​

Answer 1

Answer:

Hey dude.... Genetic drift causes evolution by random chance due to sampling error, whereas natural selection causes evolution on the basis of fitness. In natural selection, individuals whose heritable traits make them more fit (better able to survive and reproduce) leave more offspring relative to other members of the population.

Hope it helps you.....

Answer 2

Answer:

A disease comes into the rabbit population and kills 98 of the rabbits. The only rabbits that are left are red and grey rabbits, simply by chance. The genes have thus “drifted” from 6 alleles to only 2. This is an example of a bottleneck effect.
