Which of the following are associated with genetic drift? Select all that apply.
1.)reduced numbers of alleles
2.)small population
3.)increased mutation
4.)increased variation
5.)large population
Which of the following are ways in which natural selection can shape the population? Select all that apply.
1.)A new mutation causes baby mice to die in their sleep.
2.)The sex of developing alligators depends on the incubation temperature of the egg.
3.)Female garter snakes mate with any male that comes by.
4.)Larger gorillas lead the tribe and produce more offspring.
5.)A disease only infects and kills people who lack certain types of white blood cells.
Ans)
1) reduced number of alleles are assosiated with genetic drift can cause gene variants to disappear completely and thus reduce genetic drift.
2) small population are also assosiated with genetic drift because its strongest effects are found in small population.
3 genetic drift enhance the rate of mutation thus showing an assosiation with each other.
5) genetic drift is related to large population because genetic drift can lead to large changes in population that even within a short period of time.
Ans 2)
3) females garter snake mate with any male snake that comes by because of the descreased population if male garter snake, because of the rapid decrease in the population of the male snakes due to lack of adaptations and were thus unable to survive.
4) larger gorillas lead the tribe and produce more offsprings because these large males have been able to adapt themselves according to the changing environment and have thus become leaders.
5) those are being infected and killed by the disease that have not adapted themselves according to the changing pattern thus according to the law of Darwin, only those who are able to survive along with the change in nature, only they will be able to survive.
