Answer to Question #113088 in Genetics for Lydia

Question

Two plants with the genotypes TT and Tt _________________.
a. would have the same phenotype. c. would have different phenotypes.
b. have all dominant alleles d. have all recessive alleles.

Answer 1

a. would have the same phenotype

The genotypes of both plants are different. One plant has a dominant and a recessive allele (Tt) while another plant has two dominant alleles. However, as both plants have dominant alleles (T), these alleles will be expressed in both plants resulting in the formation of similar phenotypes. As a result, both plants will have the same phenotypes determined by dominant allele T.
