The correct option to the following question is (d), which is 1.
- This happens due to incomplete dominance.
- When the red gene which is dominant is crossed with the white variety, then in the F1 generation, all the flowers will be heterozygous and will have pink color.
- The monohybrid cross obtained does not resemble any of either of the parent, but an intermediate progeny.
- This happens due to incomplete dominance. Incomplete dominance is the type of gene interaction in which both alleles of a gene at a locus are partially expressed, often resulting in an intermediate or different phenotype.
- Incomplete dominance occurs due to non of the two alleles of a gene being completely dominant over the other.
- It is also known as partial dominance
- Therefore, all the hybrid obtained will be of pink color.
