Wikipedia
Dihybrid cross
Dihybrid cross is a cross between two individuals with two observed traits that are controlled by two distinct genes. The idea of a dihybrid cross came from Gregor Mendel when he observed pea plants that were either yellow or green and either round or wrinkled. Crossing of two heterozygous individuals will result in predictable ratios for both genotype and phenotype in the offspring. The expected phenotypic ratio of crossing heterozygous parents would be 9:3:3:1. Deviations from these expected ratios may indicate that the two traits are linked or that one or both traits has a non-Mendelian mode of inheritance.

dihybrid cross
A dihybrid cross is a genetic cross between individuals with different variations at two genetic loci of interest. In this type of cross, the parent generation (P1) starts with four gene alternatives or alleles for two traits, and the resulting offspring can have four different combinations of these alleles. This method is used to study the inheritance of genetic traits across two generations.

Dihybrid cross
In contrast to a monohybrid cross, a dihybrid cross is a cross between F1 offspring of two individuals that differ in two traits of particular interest. For example, BB × bb. Example: B = brown. b = blue. BB = Dark brown. Bb = Brown. bb = Blue. A dihybrid cross is often used to test for dominant and recessive genes in two separate characteristics. Such a cross has a variety of uses in Mendelian genetics. For example: RRyy/rrYY or RRYY/rryy parents result in F1 offspring that are heterozygous for both R and Y. Meiosis is the cellular process of gamete creation. It is where sperm and eggs get the unique set of genetic information that will be used in the development and growth of the offspring of the mating. The rules of meiosis, as they apply to the dihybrid, are codified in Mendel's first law and Mendel's second law, which are also called the Law of Segregation and the Law of Independent Assortment, respectively. For genes on separate chromosomes, each allele pair shows independent segregation. If the first filial generation produces four offspring, the second filial generation, which occurs by crossing the members of the first filial generation, shows a phenotypic ratio of 9:3:3:1.
