• A. 1 : 1 : 1 : 1
• B. 1 : 2 : 1
• C. 2 : 1
• D. 3 : 1

Answer 1

The correct option is B 1 : 2 : 1

Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely dominant over the other allele. This results in a third phenotype in which the expressed physical trait is a combination of the dominant and recessive phenotypes.

So, the correct answer is '1:2:1'
