Answer:
Genetic variation that alter gene activity or protein function can introduce different traits in an organism. If trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
Answer:Cleft chins were believed to be a dominant trait: if two parents had cleft chins, their kids could have a cleft or might not But it turns out a cleft chin is too complicated to be simply dominant. Two parents without a cleft have kids with cleft chins way more often than predicted with this simple model.

<u>Answer:</u>
"The birds have different mating seasons" piece of evidence supports the second student's argument.
<u>Explanation:</u>
The precise timing for bird sets to successfully match varies, and the timing for distinct species develops to give the consequent chicks the best chance of survival. Speciation is the mechanism through which new species are produced. This happens when classes within an individual are separated and diverge reproductively.
Organisms contribute to the same group as per the biological species definition if they can reproduce in order to create healthy, fertile offspring. Group are divided by prezygotic and postzygotic restrictions which prevent mating or producing viable, fertile offspring from each other.
