Probability and Mendel’s  Results Cross Yy x Yy pea plants.   Chance of Y sperm uniting with a Y egg ½ chance of Y allele from sperm ½ chance of Y allele from egg Chance of Y and Y uniting = ½ x ½ = ¼ Chance of Yy offspring ½ chance of sperm with y allele and egg with Y allele ½ chance of sperm with Y allele and egg with y allele Chance of Yy =  (½ x ½) + (½ x ½) = 2/4, or 1/2
