Sexual selection can favor the evolution of elaborate traits that natural selection acts against. How does sexual selection prod
Naily [24]

Answer:

The answer is: Linkage disequilibrium at alleles controlling the sexually selected trait and fitness bind them together evolutionarily.

Explanation:

Indirect selection can be said to operate at one locus resulting in genetic correlation with another locus, which is the main goal in the selection process. During the process of sexual choice, this commonly occurs when one preferred allele diffuses because it is out of balance with other alleles, which are benefited by natural selection or sexual selection.

An mRNA sequence reads: GAA/GCU/AUA/CUA/UGU. What would the effect on the amino acid be if the second codon read GCA instead, an
Murrr4er [49]

Answer:

D) Silent mutation on second codon, third amino acid changed from ILE to ASN.

Explanation:

Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]

On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).
