B) Law of dominance

C) Inheritance of one gene

D) Co dominance

Show Answer

Answer:

Correct Answer: D

Solution:

  • In co dominance, both alleles of a pair express themselves fully in F., hybrid, so, it resembles both the parents. In incomplete dominance, the two genes of allelomorphic pair are not related as dominant or recessive, but each of them express itself partially. Law of dominance states that when a cross is made between two homozygous individuals considering contrasting trait of simple character then the trait that appear in $ {F_1} $ hybrids is called dominant. Inheritance of one gene is based on crossing between single traits.
