Question

Among the 64 offsprings(F2 generation) of a Mendelian dihybrid cross, how many will have a double homozygous recessive genotype?

Answer 1

The dihybrid cross is a cross between two different genes means a cross between two different characters.

In F2 generation - 4 phenotypes are present (yellow round, Green round, yellow wrinkled and green wrinkled)

And 9 genotypes are present (1:2:1:2:4:2:1:2:1)

So the correct answer is "Phenotypes-4, Genotypes-9".
