Which one of the following cannot be explained on the basis of Mendel’s Law of Dominance?

Options

(a) The discrete unit controlling a particular character is called a factor
(b) Out of one pair of factors one is dominant, aond the other recessive
(c) Alleles do not show any blending and both the characters recover as such in F₂ generation.
(d) Factors occur in pairs

Correct Answer:

Alleles do not show any blending and both the characters recover as such in F₂ generation.

Explanation:

According to Mendel’s law of Dominance, out of two coontrasting allelomorphic factors only one expresses itself in an individual. The factor that expresses itself is called dominant while the other which has not shown its effect in the heterozygous individual is termed as recessive. The option (c) in the given question cannot be expained on the basis of law of dominance. It can only be explained on the basis of Mental’s Law of independent assortment, according to which in a dihybrid cross, the two alleles o
