1. Mr and Mrs Burdesha are planning to start a family. However, Mr Burdesha is concerned that, as his brother was diagnosed with Colour blindness, he may be a carrier. Their GP explains how Mr Burdesha may carry the faulty gene for colour blindness using a Punnett square. Using Cc to represent a carrier, create a Punnett square using the template below to explain to Mr Burdesha his chances of inheriting the gene from his parents if both of them were carriers of colour blindness.

- A young couple went to see a genetic counselor because each had a sibling with cystic fibrosis. (Cysticfibrosis is a recessive disease, and neither member ofthe couple nor any of their four parents is affected.)a. What is the probability that the female of thiscouple is a carrier?b. What are the chances that their child will havecystic fibrosis?c. What is the probability that their child will be acarrier of the cystic fibrosis disease allele?1. A mother with blood type A has a child with blood type O, and she claims that Mister X is the father. Mister X denies that he could possibly be the father, because he has blood type B. If you were the judge presiding over this case, which of the following arguments would you find most convincing? a. Mr. X could be the father if his blood genotype is IBIB, and the mother’s blood genotype is IAIA b. Mr. X cannot be the father because a child with blood type O cannot have a parent with blood type B c. Mr. X could be the father if his blood genotype is IBi, and the mother’s blood genotype is IAi d. Mr. X cannot be the father because a parent with blood type B cannot have a child with blood type O e. Mr. X cannot be the father because the human ABO blood types are sex-linked traits 2. A monohybrid cross between two pea plants producing yellow peas, resulting in an F1 phenotypic ratio of 3:1 (three yellow pea plants to one green pea plant) indicates what about the parental pea plants?…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?
- 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.1. A disease is known to be inherited through an ADHL mode of inheritance. For a pairing of two affected individuals, what is the expected proportion of offspring that will be affected AND female? A. 0. B. 0.667. C. 0.333.4.) A man and a woman have a child. The father is blood type A, and one of his parents was blood type A and the other was blood type O. The mother is blood type B, and one of her parents was blood type B, the other type O. Both the father and the mother are carriers of the Bombay allele. (Neither of the type-O grandparents were type O because of the Bombay allele – they had the regular type O genotype.) WhataretheoddsthattheirbabywillhavebloodtypeO? WhataretheoddsthattheirbabywillhavebloodtypeAB? (Hint – for this question, you should draw out a pedigree and fill in as much as you can for the genotypes of BOTH genes that are involved.)

Explain your answer as well as constructing Punnett squares to support your answer. 4. Both the mother and father of a hemophiliac son have normal blood clotting. What are the genotypes of the…Karen and Steve each have a sibling with sickle-cell disease.Neither Karen nor Steve nor any of their parents have thedisease, and none of them have been tested to see if they carrythe sickle-cell allele. Based on this incomplete information,calculate the probability that if this couple has a child, thechild will have sickle-cell disease.
