5The diagram below shows the inheritance of Tay-Sachs, a rare disease whichleads to the destruction of neurons. It is inherited as an autosomal disorder,controlled by two alleles, (T) and (t).Key:2.5.12.5.22.5.32.5.4374reserved11SC/NSCMale without Tay-SachsFemale without Tay-Sachs526Male with Tay-SachsFemale with Tay-SachsDescribe what is meant by an autosomal disorder.How many sons do individuals 1 and 2 have?Using individuals 3, 4 and 7, explain why it can be concluded thatTay-Sachs disease is controlled by a recessive allele.Individuals 1 and 2 can produce children with three possiblegenotypes.List ALL the genotypes that have a 25% chance of being produced.In humans, haemophilia is caused by a recessive allele on theX-chromosome (X").A woman, who is heterozygous for haemophilia, marries a man withhaemophilia.Use a genetic cross to show the percentage chance of the couple having adaughter who is homozygous for normal blood clotting.Please turn o

Achondroplasia is a rare dominant autosomal defect resulting in dwarfism. The unaffected brother of an individual with achondroplasia is seeking counsel on the likelihood of his being a carrier of the mutant allele. What is the probability that the unaffected client is carrying the achondroplasia allele?
Part 1 - With use of Punnett diagrams discuss how the results of experiments carried out by Austrian monk Gregor Mendel on pea plants brought about the Law of Dominance, the Law of Segregation, and the Law of Independent assortment. Part 2 - In humans, the gene that produces the disease Sickle Cell Anaemia is recessive to the gene for healthy haemoglobin production. a) How can two phenotypically healthy parents have a child who suffers from Sickle cell Anaemia? In your answer use suitable letters to show the genotypes of the parents and construct a Punnett diagram to show all the possibilities of the children's genotypes. b) Based on the outcome of your Punnett diagram, state and explain the probability of a child being a sufferer of Sickle Cell Anaemia and the probability of a child not suffering from the disease. c) If an individual who suffers from Sickle cell disease has a child with someone who is healthy (and not carrying the sickle cell gene), what is the probability that…
Suppose two parents are healthy carriers of the sickle cell allele. The genotype of each parent is HbAHbS (HbAis the normal allele, and HbS is the sickle-cell allele).How likely is it for a child of these parents to have sickle cell anemia (HbSHbS)?
Huntington’s Disease is a dominant lethal disease that manifests later in life after many people have had children. If you were the child of a parent who was diagnosed with Huntington's, would you want to be tested for the condition? Why or why not?
Review the process of autosomal dominant inheritance by coloring the following figures. In this instance the father is affected in the mother is unaffected to illustrate the transmission of the disorder from the father to the children color the figures as described.
Review the process of autosomal recessive inheritance by coloring the following figures in this instance both parents are carriers of a treat to illustrate the transmission of the disorder from the parents to the children color the figures as described
Part B. Write the genotype for each individual person using H and h to represent the alleles. Remember to use a H? if you cannot determine what the genotype is for person with the dominant trait.
interpret using the punnett square below to both sets of parents (Parents A , Parents B, & Parents C).based on your results of filling in the boxes. What are the chances Parents A, Parents B, and Parents C will have a child with Sickle Cell? What are the chances the child will be a carrier for Sickle Cell?
2. The common grandfather of two first cousins has hereditary hemochromatosis, a recessive condition causing an abnormal buildup of iron in the body. Neither ofthe cousins has the disease nor do any of their relatives.a. If the first cousins had a child, what is the chancethat the child would have hemochromatosis?Assume that the unrelated, unaffected parents ofthe cousins are not carriers.b. How would your calculation change if you knewthat 1 out of every 10 unaffected people in the population (including the unrelated parents of thesecousins) was a carrier for hemochromatosis?

This case explores how skin color is inherited in humans, presented in the story of Catherine and Richard Howarth whose children are surprisingly light skinned compared to their Nigerian mother. Based on what you have learned about polygenic inheritance, explain how Richard and Catherine Howarth were able to produce light-skinned babies. Are the odds indeed 1 in a million? Include possible genotypes of the couple and their children to support your argument.
