Respuesta :

1. The parents are heterozygous dominant (Rr x Rr). Therefore both their phenotype has Red spots.

2. The offspring RR inherited both the dominant gene R from the parents, making the offspring Homozygous dominant (does not carrry the r Recessive gene). The phenotype is therefore Red spots.

3. The offspring Rr have Red spots. However, they carry the r recessive gene.

4. rr phenotype has no red spots. This offspring is homozygous recessive.
