In the case of co-dominance, the F₁ generation resembles:

(1) Dominant parent

(2) Recessive parent

(3) Both the parents

(4) None of the parents

F₂ generation in a Mendelian cross showed that both genotypic and phenotypic ratios are same as 1:2:1. It represents a case of 

(1) codominance

(2) dihybrid cross

(3) monohybrid cross with complete dominance

(4) monohybird cross the incomplete dominance

Genotypic and phenotypic ratios 1 : 2 : 1 in the offsprings explain the principle of 

(1) dominance

(2) blending inheritance

(3) recessiveness 

(4) All of the above

Which of the following was not explainedby the Mendel’s law of dominance? 

(1) Characters are controlled by discrete units called factors.

(2) Factors occur in pairs.

(3) Every factor has alternate forms known as alleles

(4) In a dissimilar pair of factors one member of the pair dominatesthe other.

Incomplete dominance is present in

(1) Snapdragon flower

(2) Dog flower

(3) Antirrhinum flower

(4) All of the above
