Question

this passage describes the pod shape trait in pea plants: pea plants protect their seeds in pouch - like cases called pods. some pea plants grow inflated pods, which are smooth. other pea plants grow constricted pods, which are bumpy. in a group of pea plants, some individuals have inflated pods and others have constricted pods. in this group, the gene for the pod shape trait has two alleles. the allele d is for inflated pods, and the allele d is for constricted pods. a certain pea plant from this group has inflated pods. this plant has two alleles for inflated pods. based on this information, what is this pea plants genotype for the pod shape gene? constricted pods inflated pods dd dd

Explanation:

Step1: Determine dominant and recessive traits

Inflated pods (\(D\)) are dominant over constricted pods (\(d\)). A plant with inflated pods can have either \(DD\) (homozygous dominant) or \(Dd\) (heterozygous) genotype. Since the problem states the plant has two alleles for inflated pods, and there is no information to suggest it is heterozygous (like having a constricted - pod parent), the most likely genotype is \(DD\) (assuming pure - breeding for simplicity, as in basic Mendelian genetics problems without additional context).

Answer:

\(DD\)
