Flow color in snapdragons is determined to some extent by a pair of alleles that show
incomplete dominance: red, pink, and white with pink being the heterozygous class. Flower
shape, mushroom versus normal, is determined by an independently assorting, single gene pair
where normal is completely dominant to mushroom. Two pink snapdragons with normal flowers
were crossed and produced, among 1600 total, 100 white, mushroom-flowered offspring.
What other types of offspring and how many of each are expected from this cross?

Both parents must have been RWNn
RW because they were pink and Nn because that is the only way that normal flowers could produce mushroom offspring.
Each parent can make 4 different gametes RN Rn WN Wn
The punnett square gives :
300 Red Normal
600 Pink Normal
300 White Normal
100 Red mushroom
200 Pink mushroom and
100 white mushroom.
