How does natural selection impact the gene pool?

• Natural selection impacts the gene pool by increasing benefical traits and decreasing unhelpful triats.

• Natural selection randomly changes genes without any preference.

• Natural selection only impacts genetics, it will not impact physical traits.

• Natural selection has no impact on the gene pool because they do not relate to one another.

Are the conditions of Hardy Weinberg hard to meet? Why?

• Yes, the conditions of Hardy-Weinberg are hard to meet due to forces like natural selection, mutations, and population sizes.

• No, the conditions are easy to meet because there are mutations, small populations, and random mating throughout.

• Yes, but they are often met in nature due to natural selection, gene flow, and genetic drift.

• No, they are always met in large populations because there are no mutations, random mating, or small populations.
