Question

2. How are the results of the crosses differ if the red allele was dominant over the
white allele? Explain both the Fi and F2 generations.​

Answer 1

When the red allele is dominant over the white allele, the dominant character takes on recessive features. A dihybrid cross's offspring are divided into two generations: F1 and F2.

Explanation:

• The allele for red color predominates over the allele for white color. Pink is 100% in the F1 generation, 25% in the F2 generation, and 50% in the F3 generation due to phenotype and genotype.

• When the paternal (P) generation interbreeds, the F1 generation is the resultant generation of offspring. The F2 generation is the product of the cross-mating of F1 generation offspring.
• An F1 generation is a first filial generation offspring produced by parents who are genetically separate from one another. The second filial generation of offspring is referred to as the F2 generation.

• Outbreeding causes the F1 generation, while inbreeding causes the F2 generation.
