Question

For plant stem height, the dominant allele for height is T and the recessive allele is t. What would be the genotypes, phenotypes, and offspring probabilities of a cross between a heterozygous parent for tall stem height and one that was homozygous recessive for short stem height?

Answer 1

Answer:

If a heterozygous parent for tall stem length (Tt) is crossed with a parent that is homozygous recessive (tt), then the genotypes of their offspring would be Tt and tt. In this case, the combination Tt (long stem length) would occur 50% of the time Tt, whereas the combination of tt (short stem length) happens 50% of the time.
