The self-fertilization of an F1 pea plant produced from a parent plant homozygous for yellow and wrinkled seeds and a parent homozygous for green and round seeds resulted in a pod containing seven F2 peas. (Yellow and round are dominant.) What is the probability that all seven peas in the pod are yellow and round?

Respuesta :

Answer:

There will be [tex]100[/tex]% probability that all seven peas in the pod are yellow and round

Explanation:

Let

g represent the allele for green pod and G represent the allele for yellow pod

Like wise R represent the allele for round pod and r represent the allele for wrinkled pod

Genotype of parent with yellow and wrinkled seed is ggrr

Genotype of parent with green and round seeds is GGRR

Now if a cross is carried out between GGRR and ggrr

All the off spring will have GgRr genotype

Thus, all the offspring will be heterozygous yellow and round pod.

There will be [tex]100[/tex]% probability that all seven peas in the pod are yellow and round
