Which of the following cannot be explained on the basis of Mendel's law of Dominance?
Which of the following cannot be explained on the basis of Mendel's law of Dominance?
The correct option is C Alleles do not show any blending and both the characters recover as such in F2 generation
The correct option is C:
Explanation of the correct option :
- Mendel's law of dominance states that out of two factors, only one is able to express itself in the generation and it prevents the expression of the other.
- The one which expresses itself is called the dominant gene or factor and the one which remains unexpressed is called the recessive factor or gene.
- “Alleles do not show any blending and both the characters recover as such in F2 generation” This statement cannot be explained by the law of dominance stated above.
Explanation of the incorrect options:
Option A:
Mendel stated in the law of dominance that the contrasting characters are controlled by certain units, which he called factors.
Option B:
The trait that expresses itself is called the “dominant” factor and the one which does not express itself is called the “recessive” factor.
Option D:
Mendel stated that factors occur in pairs.
Final answer: Alleles do not show any blending and both the characters recover as such in the F2 generation, this statement cannot be explained by the law of dominance.
