Concept introduction:
DNA is a long stranded structure which is present in the form of chromosome in the nucleus of cells. In DNA many genes are present, which gets translated into specific proteins. The protein function leads to a phenotype.

Albinism is characterized by the lack of a dark pigment called melanin in the hair, skin and eyes. Albinism is caused by the absence of an functioning enzyme called thyrosinase, which is necessary for the synthesis of melanin. Given this bit of information, what can you assume about the heredity pattern of this trait?
A) It is caused by a recessive allele of the gene coding for thyrosinase.
B) It is caused by a dominant allele of the gene coding for melanin.
C) It is caused by a dominant allele of the gene coding for thyrosinase.
D) It is caused by a recessive allele of the gene coding for melanin.
E) There is not enough information here to tell
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?

- Tay Sachs is a rare autosomal recessive disorder that causes mental and physical disabilities leading to death in infants. Affected individuals are lacking the enzyme hexosaminidase, causing lipids to build up in the brain.The HEXA gene on chromosome 15 codes for hexosaminidase, and a four base pair insertion in the gene results in an altered reading frame and non-functional enzyme being produced. Individuals who are carriers (heterozygotes) of the Tay-Sachs allele are not affected by the disease but appear to have increased protection against tuberculosis.The incidence of Tay-Sachs disease is much higher among Ashkenazi Jews originating from Eastern Europe than the general population of the United States. About 1 in 3 500 babies of Ashkenazi Jewish heritage are born with Tay-Sachs disease and about 1 in 30 Ashkenazi Jews are carriers compared to about 1 in 320 000 babies born with the disease and about 1 in 300 carriers in the general United States population.

- Lesch-Nyhan syndrome is due to a mutation in a gene that encodesa protein called hypoxanthine-guanine phosphoribosyltransferase(HPRT). HPRT is an enzyme that functions in purine metabolism.People afflicted with this syndrome have severe neurodegenerationand loss of motor control.

- Phenylketonuria (PKU) is a disorder caused by a defect in the gene that codes for the phenylalanine hydroxylase (PAH), an enzyme required to break down the amino acid phenylalanine. The results of a newborn screening test indicated that Jack and Jill’s baby has phenylketonuria (PKU). Neither Jack nor Jill has PKU. A DNA test indicated that there was no switching of babies - Jack and Jill are the baby's real parents. What is the probability that their next child will have PKU?arrow_forwardPhenylketonuria (PKU) is a disorder caused by a defect in the gene that codes for the phenylalanine hydroxylase (PAH), an enzyme required to break down the amino acid phenylalanine.

- A couple is planning a family, but since each has a brother having the sickle-cell disorder, they are worried that their kids might develop the disorder too. Neither of them nor their respective parents have the disorder. Which of the following will be your smartest advice as a genetic counsellor? One of four of their children can be expected to have sickle cell. It is possible that none of their kids will have the disorder, but tests should be carried out on both of them to confirm. All of their children will have sickle-cell disorder. There is no chance of any of their kids having sickle cell.arrow_forwardAlbinism is caused by an autosomal recessive allele that interferes with skin pigmentation in mammals. Two normally pigmented human parents already have an albino boy. They plan to continue to have children until they get a girl.

Explain your reasoning. b) What is the probability their first female child will be albino?
