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 anemiaallele 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 onerecessive 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 equallylikely. 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 thedominant allele and the father contributes the non-dominant allele; and one if the father contributes the dominant allele and the mother contributes the non-dominantallele). List the other two possible genotypes of the offspring.(Use a comma to separate answers as needed.)

Suppose a woman who is a carrier of sickle-cell trait (making her a heterozygote) has children with a man who is totally healthy and does not carry the gene for sickle-cell trait at all. Which one of the following is true about their potential children? (Draw a Punnett square on scratch paper if it helps you.) A) None of their children will have sickle-cell disease. B) All of their children will have sickle-cell disease. C) All of the couple's children would be heterozygous carriers like the mother.
Duchenne muscular dystrophy is sex linked and usuallyaffects only males. Victims of the disease become progressively weaker, starting early in life.a. What is the probability that a woman whose brotherhas Duchenne’s disease will have an affected child?b. If your mother’s brother (your uncle) had Duchenne’sdisease, what is the probability that you have receivedthe allele?c.

Sickle cell anemia causes hemoglobin, the oxygen - carrying molecule of red blood cells, to be misshapen resulting in disease. "H" is the normal hemoglobin allele and "h" is the allele for sickle - cell shaped hemoglobin. In order to get the disease, a person must have a recessive genotype (hh). Two people with normal red blood cells are carriers of the gene - they have m genotypes Hh. Questions: a. What are the possible genotypes of the eggs the woman can produce? b. What are the possible genotypes of the sperm the man can produce? c. What is the genotypic ration for the offspring? d. What is the phenotype ratio for the offspring? e. What is the couple's chance of having a child a sickle cell anemia?
A couple are both phenotypically normal but their son suffers from hemophilla, a sex linked recessive disorder. What fraction of their children are likely to suffer from hemophilia. what fraction are likely to be carriers.
Sickle cell anemia is caused by an individual carrying two recessive copies of the hemoglobin gene (hemoglobin gene is labeled Hb, and the recessive version is Hbs). Thus, to have sickle cell anemia, a person must have the genotype HbSHbS. A person that is HbAHbA carries two copies of the normal hemoglobin gene and does not have sickle cell anemia. A person that is heterozygous (HbAHbS) produces enough normal hemoglobin to not have sickle cell anemia but is also resistant to malaria. People that are heterozygous are called “carriers” because they carry the recessive allele but do not express the recessive phenotype. a. A couple are both resistant to malaria but do not have sickle cell anemia. Draw a Punnett square to represent this cross. b. What is the probability that the couple has three children where one child does not have a recessive allele, one child is resistant to malaria and does not have sickle cell anemia, and one child has sickle cell anemia?
In man, muscular dystrophy is a condition in which the muscles waste away during early life and may result in a shorter life expectancy. It is due to a sex-linked, recessive gene. A certain couple has five children – three boys (ages 1yr, 3yrs, and 10yrs old) and two girls (ages 5yrs and 7yrs old). The oldest boy shows the symptoms of this disease. You are their family physician and they come to you for advice. What would you tell them about the chances of their other children developing the disease?
In humans, hemophilia is a sex-linked trait. Females can be normal, carriers, or have the disease. Males will either have the disease or not (but they won’t ever be carriers). X H X H = female, non-hemophilic X H X h = female, carrier X h X h = female, hemophilia X H Y = male, non-hemophilic X h Y= male, hemophiliac a.) Show the cross of a man who has hemophilia with a woman who is a carrier. What is the probability that their children will have the disease? b.) A woman who is a carrier marries a non-hemophilic man. Show the cross. What is the probability that their children will have hemophilia? What sex will a child in the family with hemophilia be? c.) A woman who has hemophilia marries a non-hemophilic man. How many of their children will have hemophilia, and what is their sex?
Hemophilia A is caused by a recessive X-linked allele that encodes a defective form of a clotting protein. If a affected father and a mother who is known to not be a carrier have children, what percentage of female offspring will have hemophilia?
Julie (a female) has hemophilia. Based on this information, what can we say about the genotypes of her parents? If Julie has children with a normal male, what is the chance that her sons have hemophilia? What is the chance that her daughters have hemophilia? A condition called Alport syndrome is caused by a dominant X linked allele. Males who have this condition usually have kidney failure, while females who are heterozygous for the condition have blood in the urine, but usually do not have kidney failure. A male has this condition and has children with an unaffected female What percent of his daughters will show any of the symptoms? What percent of his sons will show any of the symptoms?
A form of hemophilia is caused by a sex-linked (X-linked) recessive gene. A phenotypically normal woman whose father had hemophilia marries a man who suffers with hemophilia. What is the probability that their first daughter will have hemophilia?
Sickle cell anemia is an inherited red blood cell disorder in which there are not enough healthy red blood cells to carry oxygen throughout the body. The allele that causes sickle-cell anemia is autosomal recessive (s), and the dominant allele can be represented by S.
