Answer 1

In pea plants, the allele for tall height (T) is dominant over the allele for short height (t). A pea plant that has two different alleles for height would have the genotype Tt. Since T is dominant, the phenotype (observable trait) of the plant would be tall.

The correct statement is: The phenotype for height is tall, and the genotype is Tt.
