Solution
The correct option is D Dihybrid cross
Dihybrid cross is a cross between F1 offspring of two individuals that differ in two traits of a particular interest. For example, RRyy/rrYY or RRYY/rryy parents result in F1 offspring that are heterozygous for both R and Y (RrYy). 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 as 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 identical 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.
