Explanation:
Detailed explanation-1: -The two things a Punnett square can tell you are the genotypes and phenotypes of the offspring. A genotype is the genetic makeup of the organism. This is shown by the three genetic conditions described earlier (BB, Bb, bb). The phenotype is the trait those genes express.
Detailed explanation-2: -When a heterozygous plant is self crossed with itself in a monohybrid cross, the genotypic ratio obtained is TT:Tt:tt = 1:2:1.
Detailed explanation-3: -Answer and Explanation: A tall pea plant with (TT) and a tall pea plant with (Tt) have the same phenotype but different genotypes. Phenotype is the appearance (trait), both plants appear tall.
