Question

4. In snapdragons, a gone that affects flower color has two alleles: red (R) and white

Answer 1

Answer:

See the answer below

Explanation:

a) Since the pink phenotype is heterozygous, the genotype would be RW.

b) The pink genotype is RW. Hence, a cross between two pink snapdragons will go thus:

          RW    x    RW

      RR    RW    RW    WW

Expected genotypes: 1/4 RR, 1/2 RW, 1/4 WW

Expected phenotypes: 1/4 red-flowered plants, 1/2 pink-flowered plant, 1/4 white-flowered plant.
