Apea plant that is heterozygous for the y’all phenotype can produce short offspring when self pollinating. which of the following explains why this occurs

"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 "

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.

The selective breeding helps to maintain pure breed and hence exclude the hybrids.

Selective breeding is a very commonly practiced procedure in plant management and animal husbandry. This selective breeding helps to achieve and maintain the homozygous traits of selective characters. For example, if two dogs with white colour are breed, then their progenies will be white too. Thus the selective character i.e fur color will be maintained.

In crops, if the plants with desired fruit characteristics are bred with each other then superior quality of fruits are achieved and maintained over generations. This is very essential economically too.
