How many plants are dihybrid in F2 generation of dihybrid cross :-a)On...
Explanation:
A dihybrid cross involves the crossing of two individuals that differ in two traits. The F1 generation produced from this cross is heterozygous for both traits, while the F2 generation is produced by crossing the F1 individuals with each other.
In the F2 generation, there are four possible combinations of alleles for each trait. Therefore, there are 16 possible genotypes that can be produced from a dihybrid cross. These genotypes can be arranged into four phenotypic ratios, which are:
- 9:3:3:1
- 1:2:1:2:4:2:1:2:1
- 3:1:1:3
- 1:1:1:1:2:2:2:2:4
The second ratio is the most common and represents the phenotypic ratio of a dihybrid cross involving two genes that are both incompletely dominant or codominant.
Therefore, the answer to the question is C) Four, as there are four possible combinations of alleles for each trait in the F2 generation of a dihybrid cross.
