In pea plants, smooth (S) peas are dominant over wrinkled (s) peas in the single gene controlling pea texture. A plant with smoo
OlgaM077 [116]

Answer:

Ss and ss

Explanation:

<em>Since the smooth trait (S) is dominant over the wrinkle trait (s), the genotype of the wrinkled pea parent is definitely </em><em>ss</em><em>.</em>

<em>Also, some of the progeny had wrinkled pea texture (ss). Each of the 2 wrinkled alleles must have been donated by each of the parent. It thus means that the smooth pea parent is heterozygous for the trait (</em><em>Ss</em><em>).</em>

Now, let us look at a cross between the two parents;

  Ss   x   ss

Progeny: Ss, Ss, ss, ss.

Phenotypically, 50% of the progeny are smooth peas while 50% are wrinkled.

Looking at the population of each of the phenotype resulting from the cross. 252:247 is approximately a 50:50 ratio.

Hence, the genotypes of the two parents are Ss and ss.
