Question

How many types of zygotic combinations are possible between a cross AaBBCcDd √ó AAbbCcDD??

Answer 1

Please find the answer below:

18 types of zygotic combinations are possible between a cross AaBBCcDd √ó AAbbCcDD

Explanation:

Solving theoretically;

Crossing Aa with AA, possible genotypes you'll get are, AA and Aa i.e 2 in number.

Crossing BB with bb, we only get Bb as the phenotype i.e 1 in number

Crossing Cc with Cc gives you three different genotypes, i.e 3 in number.

Crossing Dd with Dd we get three genotype i.e 3 in number.

Multiplying the possibilities= 2 x 1 x 3 x 3 = 18
