For plant stem length, the dominant allele for height is T and the recessive allele is t. If a heterozygous parent for tall stem
lubasha [3.4K]

Answer:

Tall(Tt), Tall(Tt), Short(tt), Short(tt),  50% Tall stems, 50% Short stems

Explanation:

If the Tall plant is heterozygous it means that there is a dominant allele for Tall (T), but the short (t) allele is still present. Therefore the genotype for this parent would be Tt. Homozygous means that there are two of the same allele, so in this case Homozygous recessive would be tt.The probability of offspring from these two parents can be determined from a Punnet Square or the Foil method ( which I have shown further ). Equation: Tt*tt

First-  First Terms of each parent; T*t

Outer- First Term of first parent and Last Term of second parent; T*t

Inner- Last Term of first parent and First Term of second parent; t*t

Last- Last Term of first parent and Last Term of second parent; t*t

If you need further help, let me know! :)

Good Luck -
