which term means: most common gene allele in a population?
usual

wild - type
allele

Explanation:

Question 5

When forming gametes, each gamete gets one allele from each gene pair. For the \(MM\) gene pair, only \(M\) can be passed. For the \(Rr\) gene pair, either \(R\) or \(r\) can be passed. So the possible gametes are combinations of these, which are \(MR\) and \(Mr\).

Let \(T\) (tall) be dominant and \(t\) (short) be recessive. The heterozygous tall plant has genotype \(Tt\) and the short plant has \(tt\). Using a Punnett square: \(Tt\times tt\) gives \(Tt\) (tall) and \(tt\) (short) in a \(1:1\) ratio.

The wild - type allele is the most common allele in a population. Mutated alleles are changes from the wild - type. "Usual" is too vague and "allele" is a general term.

Answer:

A. MR and Mr
