Since "T" is dominant over "t", any plant with at least one "T" allele will be tall (the dominant trait), regardless of what the other allele is. Let's look at a Punnett square for this cross:

Sonbull [250]

The answer is charged amino acid group.

<span>Grouping of amino acid into one of three categories are only based on its R group. And there is an amino and carboxyl group are present in the amino acid that are ionized so we can say that amino acid is technically charged and there is one thing to remember that Amino acids that are classified as polar, they are not having any charge.</span>
