Create a punnett square and list the ratios
1.) In cattle, the hornless condition (H) is dominant and the horned condition (h) is recessive. A bull without horns is crossed with a purebred cow with horns. What is the probability of the genotypes and phenotypes of the off spring?
2.) In humans, free ear lobes (E) is dominant over attached ear lobes (e). A man heterozygous for free ear loves marries a woman wit attached ear lobes. What is the probability their child will have attached ear lobes?
Answer question
3.) In a cactus, if you cross a plant that has red flowers with one that has yellow flowers, you produce a plant with orange flowers. Is this codominance or incomplete dominance?
