Detailed explanation-1: -In a dihybrid cross, the parents carry different pair of alleles for each trait. One parent carries homozygous dominant allele, while the other one carries homozygous recessive allele. The offsprings produced after the crosses in the F1 generation are all heterozygous for specific traits.
Detailed explanation-2: -Dihybrid Cross Vs. In other words, one parent is homozygous dominant and the other is homozygous recessive. As in a dihybrid cross, the F1 generation plants produced from a monohybrid cross are heterozygous and only the dominant phenotype is observed. The phenotypic ratio of the resulting F2 generation is 3:1.
Detailed explanation-3: -The fraction of the offspring homozygous for both recessive traits will be 1/4 times 1/4, or 1/16.
