Question

if T represents the allele for tall pea plants,and t represents the allele for short pea plants, what is the phenotype of the offspring

Answer 1

All of the phenotypes? Create a Punnett square and remember that T for tall pea plants is the dominant allele and will be the trait that is expressed when the allele is paired.

Answer 2

If it's just T and t, then the phenotype of the offspring is tall.

Answer 3

you should know the parental genotypes first in order to determine the genotypes and phenotypes of the offspring.
