Question

Flower color in snapdragons is due to a gene with incomplete dominance: CRCR plants have red flowers, CRCW have pink flowers, and CWCW plants have white flowers. What types and ratios of flower color are expected among the progeny of a pink × white cross?

Answer 1

1 pink : 1 white

Step-by-step explanation:

The genotype of the pink snapdragon plant is CRCW and that of the white snapdragon plant is CWCW. The pink plant with genotype CRCW would produce two types of gametes in equal proportion while the while parent plant would produce all the same type of gametes having only the CW allele. The random fusion of gametes of two parents would give the progeny in following phenotype ratio= 1 pink: 1 white
