In pea plants, yellow seeds are dominant to green. If a heterozygous yellow seeded plant is crossed with a green seeded plant, what ratio of yellow and green seeded plants would you expect in F_{1} generation?

Solution & Step-by-step Explanation

This is a monohybrid test cross (Y y \times yy).The gametes from Y y are Y and y .The gametes from yy are only y .Offspring: Y y (Yellow) and yy (Green) in a 1 : 1 ratio, which is 50% : 50% .
