What is the answer of the question number 1,2 and 3? 1. A breeder performed a testcross to find out if his male dog was a purebred black. He got onebrown puppy and seven black puppies, did he have the purebred? (explain) What was thegenotype of the female dog he used in test cross (BB), (Bb), or (bb)? (explain)2. What is the different between incomplete dominance and co dominance?3. What is the phenotype and genotype of offspring in the following conditions? (use thePunnett square)- An albino man and a heterozygous woman with normal pigmentation?- A color blind woman with a man with normal vision?- A man with blood type A and woman with blood type B (both heterozygous)?- Palomino is a color in horses, (a gold coat); Genetically, the palomino color is created bya cream gene and a "red" (chestnut) base coat. A breeder want to produce only Palominohorses. What color horses he had to use for breeding? (use the Punnett square) What is thepattern of inheritance? (complete dominance, incomplete dominance, co-dominance,recessive)

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
