In 4 o’clock flowers, red is dominant to white, but the heterozygote is pink. what is the phenotype ratio of crossing red 4 o’clock flowers and pink 4 o’clock flowers?

The phenotype ratio of crossing a red 4 o’clock flowers and pink 4 o’clock flowers is 2 red 4 o'clock flowers : 2 pink 4 o'clock flowers.

Explanation: Let R represent the allele for red flowers and r represent the allele for white flowers. From the information given, R is dominant while r is recessive. A pink flower is heterozygous and have a genotype of Rr. Therefore a cross between a red flower and a pink flower will produce 2 red 4 o'clock flowers (2 RR) and 2 pink 4 o'clock flowers (2 Rr).

RR will manifest as red flowers because R is dominant gene while Rr will manifest outwardly as pink because it is heterozygous.
