Detailed explanation-1: -Their phenotype would be short. The second parent is heterozygous, so their genotype would be Tt, and their phenotype would be tall.
Detailed explanation-2: -An organism can be either homozygous dominant ( TT ) or homozygous recessive ( tt ). If an organism has two different alleles ( Tt ) for a certain gene, it is known as heterozygous (hetero-means different).
Detailed explanation-3: -One out of three of the yellow pea plants has a dominant genotype of YY, and 2 out of 3 has the heterozygous genotype Yy. The homozygous recessive plant has the green phenotype and the genotype yy.
Detailed explanation-4: -The notation tt means the homozygous condition, wherein the homologous pair contains same alleles of a gene.
Detailed explanation-5: -a homozygous tall pea plant will have the genotype TT. A homozygous short pea plant will have the genotype tt.
