Question: Think about the following two unlinked genes in the poisonous plant, Jimson Weed. The dominant allele V produces violet petals while the recessive allele v produces white petals. The dominant allele P produces prickly capsules while the recessive allele p produces smooth capsules. A true-breeding violet, smooth plant is crossed to a true-breeding white, prickly plant. What is […]
