Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Produces a phenotype that is intermediate between the two parents (a “mixture” of the two forms of the trait)
A
hybrid
B
incomplete dominance
C
pink
D
red
Explanation: 

Detailed explanation-1: -The phenomenon in which two true-breeding parents crossed to produce an intermediate offspring (also known as heterozygous) is called incomplete dominance. It is also referred to as partial dominance or intermediate inheritance.

Detailed explanation-2: -INTERMEDIATE PHENOTYPE is a phenotype of an offspring expressing a mixture of the phenotypes of the parents.

Detailed explanation-3: -An intermediate phenotype (often referred to as an endophenotype) is a quantitative biological trait that is reliable and reasonably heritable, ie, shows greater prevalence in unaffected relatives of patients than in the general population.

Detailed explanation-4: -A monohybrid cross occurs between two parents who are both homozygous and so will produce only one phenotype in their offspring. It can also occur when the genotypes of both parents are completely dominant or completely recessive, which, for certain genetic traits, will produce the opposite phenotype.
