This is a dihybrid cross in which both parents have the following gametes: PL, Pl, pL, pl.
A dihybrid cross produces #16# possible genotypes, some of which repeat.
The expected genotypic ratio for this dihybrid cross is:
#1:2:2:4:1:2:1:2:1#,
with the following expected genotypes, out of #16#.
#1/16"PPLL":##2/16"PPLl":##2/16"PbLL":##4/16"PbLl":##1/16"PPll":##2"Ppll":##1/16"ppLL":##2/16"ppLl":##1/16"ppll"#
This will produce a phenotypic ratio of: #9:3:3:1#. This means #9/16# of the offspring are expected to have both dominant traits, #3/16# of the offspring are expected to have the first trait dominant and the second trait recessive, #3/16# of the offspring are expected to have the first trait recessive and the second trait dominant, and #1/16# of the offspring are expected to have both recessive traits.
