what is genetic drift how genetic drift provides diversity without any other adaption
Answers
Answer:
genetic drift provides diversity without any adaptations. Genetic drift is a mechanism of evolution that occurs by random chance rather than natural selection. Ingenetic drift , a population experiences a change in the frequency of a given allele, prompted by random luck rather than a need for adaptation.
Answer:
1.Changes in the frequency of genes in small populations, due to accidents is known as " Genetic drift"
2.A colour variation occurered in red colour beetles which are living on green coloued leaves of bushes.
3. it results in " blue" colour beetles instead of red colour beetles and passed its colour to its progeny.
4. initially in the population, there are few blue beetle, but most are red.
5. Imagine at this point, an elephant comes by and stamps on the bushes where the beetles live
6. This kills most of the beetle sbut by chance a few beetles survived are mostly blue.
7. Agaion the beetle population slowly increases, but in the beetle population most of them are in blue colour.
8. thus genetic drift provides diversity without any adaption
