Punnett square 4

This is Incorrect!

Dr. Foster: ‘I see that you picked punnet square 4. That choice doesn’t reflect the correct genotypes for the F1 generation we established. Remember, if all F1 offspring are heterozygous Aa, producing an AA genotype in that initial cross isn’t possible. Moreover, without aa appearing in the F2, we can’t observe any white flowers at all, which contradicts our expectation from Mendel’s 3:1 ratio. Let’s go back and select Punnett square 3 at NODE 20 to ensure our predictions align with Mendel’s results.’
