Question

In snapdragons, red flower color (R) is incompletely dominant over white flower color (r). The hybrids or heterozygous plants (Rr) are pink in color. 

a) Show the genotype for a white flower and for a red flower.


b) If a red-flowered plant is crossed with a white-flowered plant, what are the genotypes and phenotypes of the F1 generation plants? 


c) What genotypes and phenotypes will be produced in the F2 generation? 


d) How did the genotypic and phenotypic ratio compare to each other in this incomplete dominance cross?


e) What would the phenotypic ratio have been if this had been complete dominance?


f) What kind of offspring can be produced if a red-flowered plant is crossed with a pink-flowered plant? 


g) What kind of offspring is/are produced if a pink-flowered plant is crossed with a white-flowered plant?

Expert Solution
Step 1a

 In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype. Thus blending occurs in incomplete dominance.
