1. In Harry Potter movies, Harry Potter can perform magic. His father can do the same but his mother cannot. What is the genotype of Harry's mother? 2. Hermione's parents are muggles (cannot perform magic). How is it possible for Hermione to do magic? What are the genotypes of her parents? Is the ability to perform magic dominant or recessive? 3. Hagrid is a half-giant. If his father was a giant, what is the phenotype of his mother? Which trait is dominant?

1. A woman is colorblind. Construct a Punnett square and using versions of the letter “C” determine if she marries a man with normal vision: What are the chances her sons will be colorblind? What are the chances her daughters will be colorblind? What are the chances of having a carrier daughter? 2. Both the husband and wife have normal vision. Their son is colorblind. What can you conclude about the father’s genotype? What about the mother’s genotype? Father: Mother: 3. If a young girl has fragile X syndrome, a recessive trait (f), what is her genotype? What are the possible genotypes of her father and mother?

1. Mary and Joe are both healthy individuals. Joe has a mother who suffered from cystic fibrosis, an autosomal recessive disorder. Mary has been genetically tested in order to find out if she has the allele responsible for this disease and her tests came out positive. They are planning on having two children together in the near future. What is the probability that she and Joe will have either 2 boys who have the disorder, OR that they have one boy who has the disorder and one boy who does not? (in other words, what is the probability that any of these two outcomes takes place? a) 1/8 b) 1/16 c) 3/32 d) 1/64 e) 9/64
1. If a man, dominant homozygote for tongue rolling, is expecting a child with a woman that is heterozygotic for the trait – what is the probability for their firstborn to be a daughter being dominant homozygotic for tongue rolling? 2. A color-blind female is expecting with a color seeing male – what is the probability of a male child to see color? 3. In Sweden 1/500 are born with an autosomal recessive disorder called thalassemia. What is the carrier frequency within the population?
1. Red-green colorblindness is caused by a recessive allele (x) at an X-linked gene, and albinism is caused by a recessive allele (a) at an autosomal gene. A phenotypically normal woman (Sara) has a father who is colorblind, and she knows that she is a carrier for albinism. She plans to have a child with a colorblind man (Abdul) who is also a carrier for albinism. What is the probability that Sara and Abdul's child will have one of the conditions, but not both? (C. Follow the steps below to answer this question. a) What is the cross? b) What are the target genotypes? Note: it might be useful to come back to this one and double- check it after you have completed step c, below. Break this down to the single gene level by answering the following questions: a. What is the proportion of normal to albino offspring? Show the Punnett square: b. What is the proportion of normal to colorblind offspring? Show the Punnett square: d) What is the probability that Sara and Abdul's child will have one…
4. Mr. Salazar has Type A blood while Mrs. Salazar has Type B. They have four children. Bobbie has Type A, Gabbie has Type B, Alex has Type AB, and Teddie has Type O. What are the genotypes of all six people in this family? NOTE: The ABO blood type gene has three alleles. IA and IB are codominant; i (for Type O) is recessive to both.
6 Huntington's disease causes damage to the nervous system. It is an inherited condition caused by a dominant allele (H). Only individuals who are homozygous for the recessive allele (h) are protected from the disease. The diagram shows the inheritance of Huntington's disease in a family.

The first one has been done for you. Number of people who fit the description Description male 7 female with Huntington's disease homozygous recessive heterozygous homozygous dominant
5. A female child, Della, has the autosomal dominant condition of polydactyly. Della's mother has the normal number of fingers and toes like her parents and brother (Della's maternal grandparents and uncle). Della's father has six fingers on each hand and so did two of his three sisters and his mother (Della's paternal aunt and grandmother). Della has a younger brother who has the normal number of fingers and toes. Give the genotype of each parent and each child. Della's Mother Della's Father Della Della's Brother 5.

12. A. B. C. A certain type of migraine headache (M) is dominant to no migraines (m). What is the genotype of a man who has migraine headaches if his father did not have them? What is the genotype of a man who has migraine headaches if his mother did not have them? If a woman without migraines marries a man who is heterozygous for migraines, what would you expect for the genotypes and phenotypes of their children? If two people who are heterozygous for migraines marry and have children, what would you expect for the genotypes and phenotypes of the children.
1) having dimples D is dominant over not having dimples d. A dimples woman whose father had no dimple and whose mother did have dimples marries a man whose mother had no dimples, whose whose father had no dimples and whose grandparents on his father's side did have dimples. What is the genotype of the woman what is the genotype of the man 2) Deafness in cocker spaniels is inherited.The allele for deafness is recessive to the allele for normal hearing. Two cocker spaniels with normal hearing are mated together. They produce a little of eight puppies, two of which are found to be deaf. Give the genotype of the parent. How many of the puppies will be unable to produce deaf offspring
9. Red-green color blindness is inherited as an X-linked recessive (Xc). If a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? In your answer, specify in your phenotype descriptions the gender of the children. (For example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons would be colorblind. Note that this is not a correct answer; it is just to give you an idea of how to explain the correct phenotypes of the cross.)___
