Question rewritten
"A pea plant that is heterozygous for the tall phenotype can produce short offspring when self pollinating. Which of the following explains why this occurs
"
Answer:
The plant carries an allele for the short phenotype, which is recessive
Explanation:
Although we do not have the options, we can explain why this occurs as follows:
If the genotype of the peaplant is Tt, where T is the dominant tall allele, and t is the recessive short allele.
A punnet square of the cross is shown.
The possible genotypes are TT (25%), Tt (50%) or tt (25). TT and Tt genotypes would produce tall plants, tt genotypes would produce short plants. Therefore, it is possible for a heterozygous tall plant to produce short plants.
