The inheritance of flower colour in the __________ is a good example to understand incomplete dominance
1 Dog flower
2 Snapdragon
3 Antirrhinum sp

The \({F_2}\) generation offspring in a plant showing incomplete dominance, exhibit :
1 Similar phenotypic and genotypic ratios of 1:2:1
2 A genotypic ratio of 1:1
3 A phenotypic ratio of 3:1
4 Variable genotypic and phenotypic ratios
Explanation:
The \({F_2}\) generation offspring in a plant showing incomplete dominance, shows similar phenotypic and genotypic 1:2:1 ratios. This ratio confirms the law of segregation.

In Incomplete dominance the recessive trait is seen due to
1 Non-functional enzyme
2 No enzyme is produced
3 Both 1 & 2
4 None of them
Explanation:
The recessive trait is seen due to non-functional enzyme or because no enzyme is produced.

\({F_2}\) generation in a Mendelian cross showed that both genotypic and phenotypic ratios are same as 1:2:1. It represents a case of :
1 Dihybrid cross
2 Multiple allelism
3 Monohybrid cross with complete dominance
4 Monohybrid cross with incomplete dominance
Explanation:
In Mirabilis jalapa which produces red flowers (RR) when they are crossed with plants having white flowers (rr), the \({F_1}\) plants (Rr) produce pink flowers. Although when such \({F_1}\) hybrid plants are self fertilized or crossed, the resultant \({F_2}\) plants are of 3 kinds on the basis of colour of the flower they bear. Thus the phenotypic ratio of plants with red: pink: white colour is 1:2:1 respectively. The effect of dominant character ( i.e., red colour) is incomplete in the hybrid pink flowered plants due to the diluting effect of recessive character (i.e., white colour) .
