Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In dihybrid cross, when F1 plants (RrYy) are self hybridised, 12 yellow and 4 green seeds are produced. Therefore the ratio of segregation of yellow and green in F2 is 3:1

Dihybrid Cross
A genetic cross between two individuals who have homozygous or heterozygous genotypes for two features or traits is called a dihybrid cross. The traits of these individuals are mainly identified by genes. The parents in a dihybrid cross experiment carry different alleles for each trait where one would be a homozygous dominant allele and the other would be a homozygous recessive allele.
For example,
A classic example of a dihybrid cross is Mendel’s experiment with peas. The experiment was done to highlight whether there is any relationship in existence between various pairs of alleles.
