A woman has a rare abnormality of the eyelids called ptosis, which prevents her from opening her eyes completely. This condition is caused by a dominant allele, The woman’s father had ptosis, but her mother had normal eyelids. Her father’s mother had normal eyelids. What are the genotypes of the woman, her father, and her mother? What proportion of the woman’s children will have ptosis if she marries a man with normal eyelids?

Hemophilia is called "the royal disease" because many European royal families had members with the condition. Hemophilia is a recessive, X-linked disorder. Queen Victoria was unaffected by hemophilia, but was a carrier of the hemophilia gene (X X ). Suppose Queen Victoria's husband, Prince Albert, was affected with hemophilia (X Y). What is the percent probability that a son of Queen Victoria and Prince Albert would be unaffected by hemophilia? probability of unaffected son: What is the percent probability that a daughter or son of Queen Victoria and Prince Albert would be affected by hemophilia? probability of affected child: What is the percent probability Queen Victoria and Prince Albert would have two affected females? probability of two affected females: % % %
A gene is composed of two alleles. An allele can be either dominant or recessive. Suppose that a husband and wife, who are both carriers of the sickle-cell anemia allele but do not have the disease, decide to have a child. Because both parents are carriers of the disease, each has one dominant normal-cell allele (S) and one recessive sickle-cell allele (s). Therefore, the genotype of each parent is Ss. Each parent contributes one allele to his or her offspring with each allele being equally likely. Complete parts a) through c) below. a) Genes are always written with the dominant gene first. Therefore, there are two instances the offspring could have genotype Ss (one if the mother contributes the dominant allele and the father contributes the non-dominant allele; and one if the father contributes the dominant allele and the mother contributes the non-dominant allele). List the other two possible genotypes of the offspring. (Use a comma to separate answers as needed.)
Albinism is inherited through a recessive allele (a). Juan has normal skin color. His Mom and Dad also have normal skin color. Juan marries Paige, who also has normal skin color. Surprisingly, their first child is an albino. What is everyone's genotype?
Red-green color blindness is inherited through an X-linked, recessive allele (b). Two parents, Fred and Ginger, have normal vision. They have two daughters, Takiyah and Kelly, who also have normal vision, and a color-blind son, David. 3. Daughter Kelly has a color-blind son, Kevin. Daughter Takiyah has five sons, all with normal vision. What are the genotypes of all the individuals? Show all your work! Fred Ginger David Takiyah Kelly Kevin Takiyah's five sons If Kelly marries a man with normal vision, what is the probability that she'll have a color-blind son? a color-blind daughter?
Hemophilia is a sex-linked trait. A person with hemophilia is lacking certain proteins that are necessary for normal blood clotting. Hemophilia is caused by a recessive allele so use "N" for normal and "n" for hemophilia. Since hemophilia is sex-linked, remember a woman will have two alleles (NN or Nn or nn) but a man will have only one allele (N or n). A woman who is heterozygous (a carrier) for hemophilia marries a normal man: a.What are the genotypes of the parents? b.What is the probability that a male offspring will have hemophilia? c. What is the probability of having a hemophiliac female offspring?
People with trisomy 21 develop Down’s syndrome. What law of Mendelian inheritance is violated in this disease? What is the most likely way this occurs?
If a father has Marfan syndrome, a dominant disorder, and passes it down to all of his children, but his wife does not have the disorder, what would the punnett square between the father and mother look like? Why is this his genotype if all of his children had Marfan syndrome?
Sickle cell anemia is a blood disorder that is expressed with incomplete dominance. The homozygous recessive phenotype has sickle shaped red blood cells that cause anemia and often death if untreated. If an unaffected father and mother move to the United States from Sub-Saharan Africa and several of their offspring have sickle cell anemia, what do we know about both parents' genotypes? One is homozygous recessive, the other is heterozygous They are both heterozygous They are both homozygous recessive One is homozygous dominant, the other is heterozygous
Huntington's disease is an inherited autosomal dominant disorder that can affect both men and women. Imagine a couple has had seven children, and later in life, the husband develops Huntington's disease. He is tested and it is discovered he is heterozygous for the disease allele, Hh. The wife is also genetically tested for the Huntington's disease allele, and her test results show she is unaffected, hh. What is the percent probability that the first child of this couple will have Huntington's disease? probability: % What is the percent probability that two of the seven children will have Huntington's disease? probability: %
hemophilia is a sex linked recessive disease. Dick does not have hemophilia. His wife Debi is a heterozygote. They are having fraternal twins, one of each sex, who they have named Dick Jr. and Debi Jr. What are the chances of Dick Jr. having hemophilia? Debi Jr.?
