Using a punnett square - you write the possible gamete combinations of one parent across the top and those of the other down the side.
By filling in the square, you determine all the possible allele combinations of the offspring.

A dihybrid cross results in 16 boxes for the offspring. For example, the cross RrDd X RrDd is shown below:RDRdrDrdRDRRDDRRDdRrDDRrDdRdRRDdRRddRrDdRrddrDRrDDRrDdrrDDrrDdrdRrDdRrddrrDdrrdd
In a fully heterozygous dihybrid cross, each parent carries two different alleles for each of the two traits being studied. The resulting offspring will have a 9:3:3:1 phenotypic ratio due to independent assortment of alleles. This type of cross can help to determine the potential genotypes and phenotypes of future generations.
To perform a Dihybrid cross, you first need to identify the genotype of both parent organisms. Then, create a Punnett square to predict the genotypes of their offspring. Finally, analyze the resulting genotypes to determine the possible phenotypic ratios of the offspring.

In a dihybrid cross, each box represents 1/16 or 6.25% of the total possible outcomes. This is because there are 16 possible combinations of alleles that can result from crossing two heterozygous parents for two traits.

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

dihybrid cross
The plant with genotype GGKk can produce two types of gametes: GK and Gk. This is because each parent contributes one allele per gene to the offspring, resulting in a total of four possible gametes when considering two different genes.
The phenotypic rationof a dihybrid cross is 9:3:3:1
In a dihybrid cross, each box represents 1/16 or 6.25% of the total possible outcomes. This is because there are 16 possible combinations of alleles that can result from crossing two heterozygous parents for two traits.
Rr x Rr is an example of a monohybrid cross, specifically a cross between two heterozygous individuals for a single trait. This type of cross helps determine the possible genotypic and phenotypic outcomes for the offspring.
In a dihybrid cross between two heterozygous individuals, there are 16 phenotypically different types of offspring possible. This is because there are 2^4 = 16 possible combinations of alleles that can be inherited from the parental generation.
A monohybrid cross involves the study of one trait or gene, whereas a dihybrid cross involves the study of two traits or genes simultaneously. In a monohybrid cross, only one pair of alleles is considered, while in a dihybrid cross, two pairs of alleles are considered.
