Question

How many different phenotypical combinations are possible using just 5 traits?

Answer 1

The When we cross AaBb with AaBb ( dihybrid cross).

we get 4 diff phenotypic combinations for a trihybrid cross we get 8 different phenotypes.

so the formula is 2 to the power n.

if 5 traits are there nos of phenotype will be 2 to the power 5 and 32. nos of phenotype for n number of traits is 2 to the power n so for 5 traits its 32.

nos of phenotype = 2 to the power n .

(n= nos of traits).

nos of phenotype = 2 to the power 4 is 16.

hence for pentahybrid cross it's 32.
