If both parents are heterozygous for height (Tt), then the ratio of the genotype is 1TT : 2Tt : 2TT and the phenotype of the offspring is 3 tall : 1 short.
A cross between parents is heterozygous for height (Tt), where T is the dominant gene and t is the recessive dominant. The gametes formed from the two parents are T and t.
Offspring produced by crossing heterozygous parents with height (Tt), allows them to have three types of genotypes namely TT, Tt, and tt with a ratio of 1:2:1.
The phenotypes of these offspring were 3 tall of 4 offspring and 1 short of 4 offspring. The ratio can be written 3: 1
