If two purple-flowered offspring resulting from a cross between homozygous dominant and white-flowered parents are crossed, what percentage of the progeny are expected to have the dominant phenotype?arrow_forwardIn pea plants, inflated pod is governed by a completely dominant gene and a constricted pod by a recessive gene. Another independently segregating dominant gene produces green pod while recessive gene produces yellow pod. Give the genotypes of the parents in each of the crosses given below.arrow_forward
