You can figure it out by looking at a sequence of rocks to try to decipher the times that an event occurred relative to the other events represented in that sequence.

(2) Do you know how old the layers are in years? so yeah séquences haha

How does the recesive sickle-cell allele stay in the gene pool
Zina [86]

Answer:

Because natural selection selects for it. Thus it persists.

Explanation:

You have to understand heterozygote advantage. Basically, it's where heterozygotes have an advantage over homozygotes. In the case of sickle cell disease, heterozygotes have an advantage, and natural selection favors whatever is advantageous. Thus, because heterozygotes each have one recessive sickle-cell allele, as natural selection favors the heterozygotes, the recessive sickle-cell allele persists and remains in the gene pool.

Whitepunk [10]

<u>Answer</u>: Option A

<u>Explanation</u> :
