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:

The phenotypic rationof a dihybrid cross is 9:3:3:1
A dihybrid cross results in 16 boxes for the offspring. For example, the cross RrDd X RrDd is shown below:RDRdrDrdRDRRDDRRDdRrDDRrDdRdRRDdRRddRrDdRrddrDRrDDRrDdrrDDrrDdrdRrDdRrddrrDdrrdd
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.
dihybrid cross
A dihybrid cross, which involves the inheritance of two different traits, can predict the genetic outcomes for two characteristics in offspring. This type of cross allows for the study of independent assortment and genetic recombination.

turd
It is a dihybrid cross.An example: if you cross garden peas having round yellow seeds with others having wrinkled green seeds, that is a dihybrid cross, because you are tracking both seed shape and seed color.
A dihybrid cross involves breeding two organisms that differ in two characteristics controlled by different genes. This cross helps understand the inheritance pattern of multiple traits simultaneously and allows for the prediction of offspring genotypes and phenotypes based on the principles of Mendelian genetics.
