A) variable genotypic and phenotypic ratio
B) a genotypic ratio of 1 : 1
C) a phenotypic ratio of 3 : 1
D) similar phenotypic and genotypic ratio of 1 : 2 : 1
Correct Answer: D
Solution :
In incomplete (partial or intermediate) dominance the effect of dominant allele is diluted or modified, so that the phenotypic expression of the concerned trait in a hybrid is distinguishable from both parental type. Consequently both phenotypic and genotypic ratios in \[{{F}_{2}}\]generation are 1:2 :1. For example when Red and white flowered plants of Mirabilis jalapa has crossed, the \[{{F}_{1}}\] progenies show pink flower.You need to login to perform this action.
