<h3>WHAT IS INCOMPLETE DOMINANCE?</h3>
Incomplete dominance is a type of inheritance in which two alleles of a gene are neither dominant or recessive, hence, a intermediate phenotype is produced.
According to this question, in snapdragons, petal color is inherited through incomplete dominance with the possible colors being red, white, and pink.
If two pink flowered plants are crossed i.e. Pp × Pp, the genotype of the offsprings that will be produced as follows:
- PP (1) - red flower
- Pp (2) - pink flower
- pp (1) - white flower
Therefore, the chance of getting a red flower if two pink flowered plants are crossed is 25% or ¼.
