Answer:
Answer is C.
Explanation:
For A and B, a base substitution affects one of the three bases that comprise a codon, the DNA/RNA unit that corresponds to a particular amino acid. If one base is substituted, one codon and therefore one amino acid will be affected. Codons have built-in redundancy, so even by changing one base, the new codon sometimes still corresponds to the same amino acid. Therefore, a base substitution at most affects one amino acid, and sometimes doesn't affect it all.
Frameshift mutations cause a lot more trouble. These occur when you have a deletion or insertion that changes the number of bases in your gene. As a result, the "frame" of the codons changes (everything shifts one way or the other by the number of bases added/removed). This affects EVERY codon downstream of the mutation, so you can imagine that such a mutation would have a bigger effect the closer to the start of the gene it occurs. This is why C is correct.
Answer:
The answer is letter D
Explanation:
The answer is the letter d) all of the above could be studied with quantitative genetics since quantitative genetics seeks the main gene receptors apart from the assessment of all descendant phenotypes, not only is it considered the most recent but also the occlusion of the older and its strongest gamete at the time of the genetic cross, so any study that relates to the genetic characteristics of the animals either the shape of their body, their color, and even their evolution has to do with quantitative genetics
The metabolism converts nutrients into energy or materials for growth, reproduction, repair, and maintenance.
