In plant height, the tall allele (T) is dominant to the short allele (t). From a cross between two heterozygous plants [Tall (Tt) x tall (Tt) = 3/4 tall (T_) and 1/4 short (tt)], you generate 282 tall progeny.

In pea plants, tall (T) is dominant and short (t) is recessive. A heterozygous tall plant is crossed with a short plant. What is the expected phenotypic ratio? all offspring will be tall 3:1 1:2:1 9:3:3:1 1:1 all offspring will be short

The dominant allele for tallness in plants is T, while the recessive allele for shortness is t. If a plant has TT as its genotype, its phenotype will be that it is tall.
