In some bees, thin stripes (S) are dominant over thick stripes (s) and black eyes (B) are dominant over gray eyes (b). Complete a dihybrid cross for parents with the genotypes: SsBB × ssBb and answer the following in complete sentences.
1.Describe how you would set up a Punnett square for this cross.
2.List the likelihood of each possible offspring genotype.
3.List the likelihood of each possible offspring phenotype.

Please tell me if my answers are correct? I think you would do a 2X2 punnet square. And that the SsBB can produce two kinds of gametes which are SB and sb
And that the ssBb can produce two kinds of gametes which are sB and sb

So there would be 25% SsBB, 25% SsBb, 25% ssBb, and 25% ssbb. Are all of these correct?
