Best Answer

A dihybrid cross has the possible gamete combinations of one parent across the top, and those of the other parent down the side. The possible allele combinations for the offspring are then filled into the middle of the square.

For example, the punnett square for the dihybrid cross RrDd X RrDd is shown below:

RD

Rd

rD

RRDD

RRDd
