Answer:
Expected outcome: HH, Hh, Hh, and hh
The phenotypic ratio of the offsprings will be 3 hairy stems : 1 hairless stem
Explanation:
This question involves a single gene coding for possession of hair on stems or not in tomato plants. The allele for hairy stem (H) is dominant over the allele for a hairless stem (h).
According to this question, if two tomato plants that are heterozygous for hairy stems (Hh) are crossed, the following gametes will be produced by each parent: H and h. Using these gametes in a punnet square, the following proportion of offsprings will be produced:
HH, Hh, Hh, and hh
3 hairy stems (HH, Hh, Hh) : 1 hairless stem (hh).
