True

Explanation:

In pea plants, inflated pea pods are the dominant trait, whereas constricted pea pods are the recessive trait.

If a plant is purebred for inflated pods, it means it is homozygous for the dominant trait (e. g. PP). If a plant is purebred for constricted pods, it means it is homozygous for the recessive trait (e. g. pp).

Each offspring inherits one allele from each parent, meaning they have to inherit a P allele from the inflated pod parent (because that is all they have to pass on), and they have to inherit a p allele from the constricted pod parent (because that is all they have to pass on).

Therefore all offspring will be heterozygous Pp. Becauese inflated pods are dominant, all offspring will be inflated pod offspring and the answer is true.
