- In a maternity ward, four babies become accidentallymixed up. The ABO types of the four babies are known tobe O, A, B, and AB. The ABO types of the four sets ofparents are determined. Indicate which baby belongs toeach set of parents: (a) AB × O, (b) A × O, (c) A × AB,(d) O × OIn humans, free ear lobes (E) is dominant over attached ear lobes (e), and brown eyes (B) is dominantover blue eyes (b). A man with free ear lobes and brown eyes marries a woman with attached ear lobes andbrown eyes. Of four children, one has free ear lobes and brown eyes, one has free ear lobes and blue eyes,one has attached ear lobes and brown eyes, and one has attached ear lobes and blue eyes. Determine thegenotypes of the parents.man, assume that spotted skin (S) is dominant over non-spotted skin (s) and that wooly hair (W) is dominant over non-wooly hair (w). Cross a marriage between a heterozygous spotted, non-wooly man with a heterozygous wooly-haired, non-spotted woman. Give the genotypes and phenotype of offspring.
- For Dalmatian dogs, the spotted condition is dominant over non-spotted. (a) Using a Punnett square, show the results of a cross between two heterozygous parents. ( please draw the punnet square and write the parent and G and f1: thanks) (b) A spotted female Dalmatian dog mates with an unknown father. From the appearance of the pups, the owner concludes that the male was a Dalmatian. The owner notes that the female had six pups, three spotted and three non-spotted. What are the genotype and phenotype of the unknown male?Mexican hairless dogs have little hair and few teeth. When aMexican hairless is mated to another breed of dog, about half ofthe puppies are hairless. When two Mexican hairless dogs aremated to each other, about 1/3 of the surviving puppies have hairand about 2/3 of the surviving puppies are hairless. However,about two out of eight puppies from this type of cross are borngrossly deformed and do not survive. Explain this pattern ofinheritance.Mendel believed that gametes have only one factor for each inherited trait. Which observations supports Mendel's idea? * O diploid cells are produced by mitosis O diploid cells are produced by meiosis O haploid cells are produced by meiosis haploid cells are produced by mitosis Meiosis in animals is responsible for the formation of what type of cells?

- Mary and Ron don't have albinism. However, is it possible for them to have a child with albinism? Explain. Stephanie has normal color vision. Her husband Chris also has normal color vision. They have a son that is color blind and a daughter that has normal color vision. What is the genotype of the mother, father, son and the daughter? Andy and Anne do not have polydactyl. Is it possible for them to have a child with polydactyl? Explain. When examining a pedigree chart, I notice that only males are affected. What does this tell me about the inheritance pattern? A man with blood type A marries a woman with blood type B. Their child has blood type O. What are the genotypes of the parents?Purple flowers are dominant to white flowers. Identify the phenotypefor the following genotype Ff, FF, ff and determine if the genotype is heterozygous or homozygous. * For each row, you should select two columns.

- In cattle, coat color is inherited in a co-dominant fashion. Homozygous C R C R produces red coat,homozygous C W C W produces white coat, and the heterozygous C R C W produces roan-colored coat.What is the probability of having a roan-coated offspring in a cross between a white-coated cattle anda roan-coated cattle?In humans, free ear lobes (E) is dominant over attached ear lobes (e), and brown eyes (B) is dominant over blue eyes (b). A man with free ear lobes and brown eyes married a woman with attached ear lobes and brown eyes. Of four children, one has free ear lobes and brown eyes, one has free ear lobes and blue eyes, one has attached ear lobes and brown eyes, and one has attached ear lobes and blue eyes. Determine the genotypes of both parents.You have a purple-flowered pea plant, but you do not know if it is homozygous (PP) or heterozygous (Pp) for flower color because both genotypes result in the same purple phenotype. Purple color allel (P) is dominant over white flower allel (p). What would you do to determine the genotype of flower color of this plant? Lötfen birini seçin: O a. Crossing the plant with homozygous large flowered pea plant (LL) Ob.
