All of these choices are possible combinations in a dihybrid cross
The phenotypic rationof a dihybrid cross is 9:3:3:1
The cross RR X Dd is showing two different genes for the parents (it is showing RR for one parent and Dd for the other) - therefore this is not a dihybrid cross. However, if it was RRDd X RRDd, this would be a dihybrid cross. For a dihybrid cross, you need to include two different genes (and show these genes in both the parents). So - BbFf X bbff, GGTT X ggtt, KKPp X KkPp - are all examples of dihybrid crosses.
Yes it is indeed a dihybrid cross. I am studying this in college Bio I right now.
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:RDRdrDrdRDRRDDRRDdRrDDRrDdRdRRDdRRddRrDdRrddrDRrDDRrDdrrDDrrDdrdRrDdRrddrrDdrrdd
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.
A dihybrid cross involves crossing organisms that are both heterozygous. In the dihybrid cross the allele for two different traits assort independently which means the outcome for one trait doesnt depend on the outcome for the other trait.
