Dominance Deviation From Mendel 1

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

1.	The discrete unit controlling a particular character is called a factor.
2.	Out of one pair of factors, one is dominant, and the other recessive.
3.	Alleles do not show any blending and both the characters recover as such in the F2 generation.
4.	Factors occur in pairs.

Which Mendelian idea is depicted by a cross in which the F₁ generation resembles both the parents?
1. law of dominance
2. inheritance of one gene
3. co-dominance
4. incomplete dominance

A gene showing co-dominance has?

1.	One allele is dominant on the other
2.	Alleles are tightly linked on the same chromosome
3.	Alleles that are recessive to each other
4.	Both alleles are independently expressed in the heterozygote

In Antirrhinum (Snapdragon), a red flower was crossed with a white flower and in F₁ generation, pink flowers were obtained. When pink flowers were selfed, the F₂ generation showed white, red, and pink flowers. Choose the incorrect statement from the following:

1.	Law of Segregation does not apply in this experiment.
2.	This experiment does not follow the Principle of Dominance.
3.	The pink colour in F1 is due to incomplete dominance.
4.	Ratio of F2 is 1/4(red):2/4(pink):1/4(white).
