Question

1. what does natural selection favor?

all offspring
beneficial traits
extreme phenotypes
genotypes

Explanation:

Natural selection is a process where organisms with beneficial traits (traits that help them survive and reproduce better in their environment) are more likely to pass on their genes. It doesn't favor all offspring (as not all survive or reproduce effectively). Extreme phenotypes are often not the most adaptive in a stable environment (though in some cases like disruptive selection they can be, but generally not the norm). Genotypes are the genetic makeup, but natural selection acts on the phenotype (the observable traits). Beneficial traits increase an organism's fitness (ability to survive and reproduce), so natural selection favors them.

Answer:

beneficial traits
