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:

All of these choices are possible combinations in a dihybrid cross
The phenotypic rationof a dihybrid cross is 9:3:3:1
Yes it is indeed a dihybrid cross. I am studying this in college Bio I right now.
A dihybrid cross results in 16 boxes for the offspring. For example, the cross RrDd X RrDd is shown below:RDRdrDrdRDRRDDRRDdRrDDRrDdRdRRDdRRddRrDdRrddrDRrDDRrDdrrDDrrDdrdRrDdRrddrrDdrrdd
A dihybrid cross is the cross that involves parents that differ in two traits.

Science deals with the term dihybrid cross and it is a term that explains how two different colored parents end up with the color pattern of their offspring. The law of independent segregation is explain by dihybrid cross.
