Chapter 2, Problem 25P
The achoo syndrome (sneezing in response to bright light) and trembling chin (triggered by anxiety) are both dominant traits in humans.
a. | What is the probability that the first child of parents who are heterozygous for both the achoo gene and trembling chin will have achoo syndrome but lack the trembling chin? |

- In humans, the gene for albinism (a) is recessive to the gene for normal skin pigmentation (A). If two heterozygous persons have children, what is the probability they will have a child who is an albino? What is the probability they will have a child that is a carrier of the recessive gene?arrow_forwardNormal pigmentation in humans is completely dominant to albinism. A couple who are both carriers for albinism decided to have children. a. Given that their first offspring normally pigmented, what is the probability that the child is a carrier? b. Considering the same genotypes of parents, what is the likelihood that three albino and two are normally pigments in a brood of five?arrow_forwardIn 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.arrow_forward

What is the probability that a woman whose brother has Duchenne’s disease will have an affected child?b. If your mother’s brother (your uncle) had Duchenne’s disease, what is the probability that you have received the allele?c. If your father’s brother had the disease, what is the probability that you have received the allele?arrow_forwardIn humans, curly hair is dominant to straight hair.

- Fat mice can be produced by two independent genes. The "oo" genotype generates a fat and sterile mouse, called obese; its dominant "O" allele results in normal growth. The recessive "aa" genotype also produces a fat, sterile mouse called adipose, while its dominant allele causes normal growth. What phenotypic ratios of fat versus normal mice can we expect in F1, being the parents of the OoAa genotype?arrow_forwardA. Tongue rolling (T) is dominant over non-tongue rolling (t). Right handedness (R) is dominant over left (r). A non-tongue rolling, left-handed woman marries a tongue rolling, right-handed man who is heterozygous for both traits. What are the possible genotypes and phenotypes of the offspring? B. A tongue rolling, right-handed man marries a non-tongue rolling, right-handed woman. Their first child is non-tongue rolling and left- handed. What are the genotypes of the parents? Mom: Dad: C. A non-tongue rolling, right-handed man whose mother was left-handed marries a tongue rolling, right- handed woman whose mother was non-tongue rolling and left- handed. What are the possible genotypes and phenotypes of their children? D. In man, a certain type of deaf mutism is recessive. Let (D) be normal and (d) be deaf-mute. A normal, right-handed man married a normal, right-handed woman. They had a child who was a left-handed deaf-mute. What were the genotypes of the parents?…arrow_forwardIn humans, dark hair (D) is dominant over blondness (d), and color blindness (c) is a sex-linked recessive trait. A woman has a blond brother, a blond mother, and a dark-haired father. Her brother and her parents have normal vision. She bears the following three children by her blond, normal-visioned husband: a dark-haired son with normal vision, a dark-haired daughter with normal vision, and a dark-haired color blind son. What is the probability that her next (fourth) child will be a colorblind boy.arrow_forward

That the man in his thirties will develop Huntington disease.B. That his first child will develop Huntington disease.C. That one out of three of his children will develop Huntingtondisease.arrow_forwardIn humans, dark hair (D) is dominant over blondness (d), and color blindness (c) is a sex-linked recessive trait.
