1. Incomplete dominance governs the pigment gene of a flower. A mating between heterozygotes yields the following phenotypic ratio: 10 yellow flowers, 35 pink flowers and white flowers. Which statement describes the situation? a. The flower pigment gene is defined by a pink and yellow allele. b. The heterozygotes were yellow. c. The heterozygotes were white. d. The flower pigment gene is defined by a red and a white allele. 2. Mendel's rules do not correctly predict patterns of inheritance for tightly linked genes or the inheritance of alleles that show incomplete dominance. Does this mean that his hypotheses are incorrect? A. Yes, because they are relevant to only a small number of organisms and traits. b. Yes, because not all data support his hypotheses. c. No, because he was not aware of meiosis or the chromosome theory of inheritance. d. No, it just means that his hypotheses are limited to certain conditions. 3. Discuss the inheritance of hemophilia
