In a certain plant, yellow leaves are dominant (Y) and red leaves are recessive (y). A plant with genotype Yy and a plant with Yy are crossed. If they have four offspring, how many would you predict would have red leaves?

1 plant. This is because offspring will only have red leaves if it receives yy, and there is a 25% chance of this, so 1/4 of the offspring will be predicted to have red leaves.
