Question

what would be the genotype of a pink flowers if it follows the rule for incomplete dominance given that r=red and w=white?
A)p
B)pp
C)WW
D)red and white​

Answer 1

Explanation:

The genotype for the pink flower is Rr and the genotype for the white flower is rr. This would lead to a 50% chance of the offspring having a phenotype of pink.

Answer 2

The genotype of the pink flower will be Rw [ D) red and white].

• Incomplete dominance is a type of Non-Mendelian inheritance in which neither dominant nor recessive gene can express itself completely.
• Thus the product of such a cross is progeny that does not resemble either parent.
• In the case of Snapdragon (Antirrhinum majus), incomplete dominance is seen when red flowers are crossed with white flowers. This cross can be represented as:  

Parents                 RR                ×                    ww

                           (red)                                 (white)

                                                 ↓

$F_{1}$                                            Rw

                                              (pink)

Hence, pink flowers have the genotype Rw.

So option D) Red and white is correct.
