Question

What genotypic ratio is expected in a cross between two heterozygous parents (Pp x Pp)?3 purple: 1 white2 purple: 2 white1:2:11:3

Answer 1

1:2:1

Explanation

when we cross two heterozygous parents Pp x Pp. we can determine the genotypic ratio using a punnett square

from the punnett diagram above, we can see that we will have the following genotypes

PP

Pp

Pp

pp

so the phenotypic ratio would be

1:2:1
