In guinea pigs, black fur is dominant over brown fur, and short hair is dominant over long hair. These traits follow Mendelian inheritance. Suppose a homozygous short black hair is mated with a homozygous long brown haired rabbit, determine the phenotypic ratio of the following: F1 generation; F2 generation; F1 mated with a short brown haired rabbit. Gene Notation: B - hair color , S - hair length

A pedigree analysis was performed on the family of a man with schizophrenia. Based on the known concordance statistics, would his MZ twin be at high risk for the disease? Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?
In dogs, wire-haired (H) is dominant to smooth-haired (h). In a cross of a homozygous wire-haired with a smooth-haired dog, what will be the phenotype of the F1 generation? What would be the genotype? What would be the ratio the wire-haired dogs in the F1 generation? What are the phenotypic and genotypic ratio?
In dogs, wire-haired (S) is dominant to smooth-haired (s). In a cross of a homozygous wire-haired with a smooth-haired dog, what will be the phenotype of the F1 generation? What would be the genotype? What would be the ratio the wire-haired dogs in the F1 generation? What are the genotypic ratio and phenotypic ratio?
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?
Skin color in humans is determined by polygenic inheritance, which means the more dominant alleles there are, the darker the skin color will be. A medium-toned skinned woman (AaBb) has a child with another medium-toned skinned man (AaBb). What is the probability of them having a very dark-toned skinned child? (Hint: the genotype is homozygous dominant)
In guinea pigs, the allele for short hair is dominant.What genotype would a heterozygous short-haired guinea pig have? _____What genotype would a pure-breeding short-haired guinea pig have? _____What genotype would a long-haired guinea pig have? _____
The long hair of Persian cats is recessive to the short hair of Siamese cats, but the black coat color of Persians is dominant to the brown-and-tan coat color of Siamese. Make up appropriate symbols for the alleles of these two unlinked loci. If a pure black, long-haired Persian is mated to a pure brown-and-tan, short-haired Siamese, what will be the appearance of the F1 offspring? If two of these F1 cats are mated, what is the chance that a long-haired, brown-andtan cat will be produced in the F2 generation? (Use the shortcut probability method to obtain your answer; then check it with a Punnett square.)

If a pure black, long-haired Persian is mated to a pure brown-and-tan, short-haired Siamese, what will be the appearance of the F1 offspring? If two of these F1 cats are mated, what is the chance that along-haired, brown-and-tan cat will be produced in the F2 generation?

In humans, the genetic disease cystic fibrosis is caused by a recessive allele (a). The normal (healthy) allele is dominant (A). What is the genotype of someone who has cystic fibrosis? What are the two different genotypes that a healthy person could have? If two people were both heterozygous for the cystic fibrosis gene, what fraction of their children would be likely to have this disease? Hint: Draw a Punnett square to figure it out.
Holstein cattle suffer from the condition citrullinemia, in which homozygous recessive calves die within a week of birth because they cannot break down ammonia that is produced when amino acids are metabolized. If a cow that is heterozygous for the citrullinemia gene is inseminated by a bull that is homozygous dominant, what is the probability that a calf inherits citrullinemia?
In guinea pigs, the allele for short hair is dominant. What genotype would a heterozygous short haired guinea pig have? What genotype would a purebred short haired guinea pig have? What genotype would a long haired guinea pig have?
