Question

According to the law of dominance, out of a pair of allelomorphic characters, what relationship exists between them?

विकल्प

• Both are recessive and never expressed

• One is dominant and the other is recessive

• Both are equally expressed in the phenotype

• One is dominant and the other is codominant

Answer 1

The law of dominance fundamentally states that in a pair of allelomorphic characters, one trait is dominant (expressed) while the other is recessive (unexpressed in heterozygotes). This is the core principle governing trait expression in Mendelian genetics.
