Question

If you cross the genotype Pp with pp, the possible genotypes in offspring are

Answer 1

Pp and pp

the genotypic ratio is 2Pp: 2 pp

Step-by-step explanation:

When doing the cross you can consider the possibility of the outcome through a punnet square or probability.

A punnet square is the best option to do so, however.

Make a grade with four boxes and place one allele of one genotype over each box like this

P p

|||||||||||||||||||

---------------------------------------------------------------

|||||||||||||||||||

Add the letters of the other genotype next to the boxes.

P p

p |||||||||||||||||||

---------------------------------------------------------------

p |||||||||||||||||||

Now put one allele in the box, like you are multiplying the letters

P p

p Pp ||||||||||||||||||| pp

---------------------------------------------------------------

p Pp ||||||||||||||||||| pp

Now you have done a punnet square

Answer 2

If you cross Pp with pp this is what you will get, Pp, Pp, pp, and pp
