Solution

The correct option is C All are Yy
A monohybrid cross is a mating between two individuals with different alleles at one genetic locus of interest.
The cross between YY that produces yellow seeds and yy that produces green seeds will produce plants having genotype Yy.
Therefore, the correct answer is option B.
