Detailed explanation-1: -Phenotypes for plant height are tall or short. TT and Tt genotypes both expressed the tall phenotype because the T is dominant to t. Only the tt genotype expressed the short phenotype.
Detailed explanation-2: -Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.
Detailed explanation-3: -The homozygous dominant, homozygous recessive, and heterozygous genotypes only account for some genes and some traits.
Detailed explanation-4: -The different possible genotypes are AA, AO, BB, BO, AB, and OO. How are blood types related to the six genotypes? A blood test is used to determine whether the A and/or B characteristics are present in a blood sample.
