Colorblindness is a sex-linked traits in humans. If a normal-visioned mother and a colorblind father have 5 female offspring and 6 male offspring that are all NOT colorblind, what is likely the mother’s genotype? Why?
In humans, brown eyes (B) are dominant over blue. A brown eyed man marries a blue-eyed (b) woman and they have three children two of whom are brown-eyed and one of whom is blue-eyed. what are the possible genotypes of the children?
In humans, hair color and structure are determined by two independent pairs of genes. The dominant gene T determines dark hair color, and the recessive allele t - light hair; The dominant gene S determines the formation of curly hair, and its recessive allele t - straight hair. What kind of hair will the children have if the mother has light, straight hair, and the father has dark, curly hair (one of the pairs of traits is heterozygous for both parents)?
In humans, brown eyes (B) are dominant over blue. A brown eyed man marries a blue-eyed (b) woman and they have three children two of whom are brown-eyed and one of whom is blue-eyed. if the male has brown eyes but has a blue-eyed child, what must his genotype be?
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.
Color blindness occurs in about 8% of North American men of European descent, but only about 4% of North American men of African descent. Assuming X-linked recessive inheritance for color blindness, what frequencies of color blindness would you expect in each of these populations?
Facial dimples and free earlobes are both considered dominant human traits. What are the expected phenotypes of the offspring of a female with dimples and free earlobes (DDFf) and a male with no dimples and attached earlobes (ddff)?
Red-green colorblindness is determined in humans by a single X-linked locus. Colorblind males are XbY, and males with normal vision are XBY. XB is dominant, so XBXB and XBXb females have normal vision, while XbXb females are colorblind. Typically, 8% of males are red-green colorblind. Assuming H-W equilibrium, what percentage of females is typically colorblind?
In cats, black fur (B) is dominant over brown fur (b). Also, striped fur (A) is dominant over solid colored fur (a). What is the phenotype of a cat with the genotype Bbaa? What combinations of gametes could the Bbaa cat make? If the Bbaa cat mated with a cat that was heterozygous for both the color and pattern genes, what fraction of their kittens would be likely to have solid brown fur? Hint: draw your square on a separate paper to figure it out.
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)
Spotting in horses is a dominant trait. Cross a homozygous spotted horse with a homozygous solid-colored horse. What are the genotypes and phenotypes of their offspring?
In humans brown eye color is dominant to blue eye color. Suppose that your mother is homozygous and your father is heterozygous and you have brown eyes. If you have a child with blue eyes, what are the possible genotypes of both of your parents?
