White

This is incorrect!

Dr. Foster: “That choice isn’t correct, everyone. Recall from Mendel’s experiments that the purple flower is dominant. It appears whenever at least one purple allele is present, whereas white is recessive and only emerges if an individual has two white alleles. That explains why most of the F2 generation was purple, with only a small number turning out to be white.’

Alice: ‘So, if an allele is recessive, we only see it when it’s paired with another recessive allele. That’s why Mendel’s white flowers stopped showing up until the F2 generation, right?’

Dr. Foster: ‘Exactly. When you see a minority of offspring displaying the white trait, it confirms that white must be recessive. Purple, meanwhile, is observable even in a hybrid if just one purple allele is present.’
