In what way(s) is artificial selection different from natural selection?

Question

a. with artificial selection there does not need to be heritable variation but with natural selection there does need to be heritable variation

b. with artificial selection humans are the selective agent, but with natural selection humans are not

c. with artificial selection there is no differential reproduction, but with natural selection there is

d. with artificial selection there does need to be heritable variation and there is no differential reproduction but with natural selection there does not need to be heritable variation and there is differential reproduction

e. two of the above are true

Answer 1

b and c are the correct answers. Humans control the rate of reproduction in artificial selection so there is no differential reproduction. Below are the requirements for natural selection, one of which is differential reproduction. Hope this helps.

Here are the requirements of natural selection from https://evolution.berkeley.edu/evolibrary/article/0_0_0/evo_25

1.There is variation in traits.

For example, some beetles are green and some are brown.

2.There is differential reproduction

Since the environment can't support unlimited population growth, not all individuals get to reproduce to their full potential. In this example, green beetles tend to get eaten by birds and survive to reproduce less often than brown beetles do.

3.There is heredity.

The surviving brown beetles have brown baby beetles because this trait has a genetic basis.

4.End result:

The more advantageous trait, brown coloration, which allows the beetle to have more offspring, becomes more common in the population. If this process continues, eventually, all individuals in the population will be brown.
