In Radishes, Two Incompletely Dominant Genes Control Color and Shape

question 96

Short Answer

In radishes, two incompletely dominant genes control color and shape. Red and white radishes are homozygous, while the hybrid is purple. Long and round are homozygous and, if crossed, will produce an oval hybrid. Give the F ₂ genotypic and phenotypic ratio produced by crossing pure-breed red and long radishes with white and round varieties.
