In snapdragons, there are 3 flower colors – red, pink and white. A farmer crosses a heterozygous flower with a red flower. The farmer wants white flowers. Could the farmer get white flowers from this cross, if not then how could he get white flowers? Figure out the phenotypic and genotypic ratios of their possible offspring. Make sure to include a Punnett Square(s). Type of Dominance in problem
genotype of -
i) red flower- RR
ii) pink flower-Rr
Since , the farmer crosses heterozygous pink(Rr) with red flower (RR), the genotypes of the offspring will be-
R RR Rr he will get only pink(1:2) and red flowers(1:2) but not white.
R RR Rr
To get white flowers he must either cross white with white or white with pink.
