A species of butterflies gradually becomes darker in color over many generations; this is an example of which characteristic of
uranmaximum [27]

This is an example of directional selection.

The term "directional selection" refers to the process of positive selection in which one phenotype is chosen over another, leading the allele frequency to shift in favor of the other phenotype. It is advantageous to have the allele that directional selection favors. The rate of reproduction and the likelihood of survival both increases. Here, the rabbit population has shrunk over the years as they have become accustomed to living in burrows. The rabbits' sizes were eventually preferred. We refer to this as directional selection.

Which position in a codon shows the greatest degeneracy? In other words, if a change occurs in this codon position, it is less l
uysha [10]

Answer:

Third position

Explanation:

Degenerate nature of genetic code refers to the fact that one amino acid can be encoded by more than one triplet combinations of nucleotides. However, if an amino acid is encoded by more than one triplets, the multiple triplets for that amino acid differ from each other with respect to the type of nucleotide present at the third position. For example,  isoleucine is encoded by AUU, AUC, and AUA. The third nucleotide is different in these genetic codes.

Alternative RNA splicing...
LiRa [457]

Answer:

D) can allow the production of different proteins from a single gene.

Explanation:

Alternative splicing:

Alternate splicing is also known as alternative RNA splicing, or differential splicing. Alternate splicing is a regulated process during gene expression in which multiple proteins are produced from single gene.

Actually eukaryotic genes have both Intron and exon sequences. Exons are the sequences present inside mRNA which convert into amino acids and produces peptides while introns are the sequences which are spliced (cut) from pre mRNA.

Some time introns for some proteins becomes exons for other proteins in this ways one gene can produce multiple proteins.
