The condition in which the heterozygote has a phenotype intermediate between contrasting homozygous parents is called as:
Correct answer: B. Incomplete dominance
- A. Dominance
- B. Incomplete dominance
- C. Codominance
- D. Over-dominance
Explanation
Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism's resulting physical appearance shows a blending of both alleles.

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
