A severe form of neurological disorder. Geetas Disease, is found in indians living in New Delhi. The disease is due to a mutation that is inherited in an autosomal recessive manner. Rama and sumita do not have the disease but it runs in their family. They have one child who has geetas disease. what is the predicted fraction of their children that will have the disease?

1) 1/2

2) no chance

3) 4/4 or 100%

4) 3/4

5 1/4

1. Researchers have identified a gene in humans that (when mutant) causes severe dwarfism and mental retardation. This disorder is inherited in an autosomal recessive manner, and the mutant allele is known to be a loss-of-function mutation. The same gene has been found on mice, although a mutant version of the gene has not been discovered in mice. To develop drugs and an effective therapy to treat this disorder, it would be extremely useful to have a mouse model of...

Cystic fibrosis (CF) is a genetic disorder that affects mostly the lungs, but also the pancreas, liver, kidneys, and intestine. CF is inherited in an autosomal recessive manner with simple Mendelian inheritance. It is caused by the presence of mutations in the gene for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. A normal couple intends to have children but consult a genetic counselor because the man has a sister with CF and the woman has a brother with CF....

Phenylketonuria (PKU) is a disease that results from a recessive gene. Two normal parents produce a child with PKU. After determining the parents genotype and performing a cross, answer to the following questions: [3 pts – 1 A, 1 B, and 1 Punnett square. What is the probability of that event? The probability is 1 out of 4 or 25% chance. This couple wishes to have a large family and would like to have 5 children. What is the probability...

Squamous ampheritis is a genetic disease that leads to acute kidney failure during childhood. The disease follows an autosomal recessive inheritance pattern and has a penetrance of 80%. Clara and Matt both have a family history squamous ampheritis and genetic testing has revealed that both are heterozygous carriers of the disease allele. What is the probability that their first child will require a kidney transplant due to kidney failure from this disease? a. 2/5 b. 1/5 c. 1/4 d. 3/5...

Sickle cell disease (sickle cell anemia) is a relatively common disorder in individuals of African descent and affects approximately 1 in 500 African-Americans. Due to a mutation in an autosomal gene for hemoglobin, the homozygous recessive genotype leads to red blood cells that are relatively stiff and sticky, and deform into a sickle shape as they lose oxygen. This leads to problems in the spleen, and anemia. There are hundreds of different hemoglobin alleles. Individuals heterozygous for the sickle cell...

Part II – Genetic Basis of the Disorder As Alexander’s family and you have now discovered, spondyloepiphyseal dysplasia congenita (SEDC) is a genetic disorder in which the primary deficits are abnormal growth of one or more spinal vertebrae and the growing ends of the femurs, resulting in disproportionate, short-trunk dwarfism (Parikh & Crawford, 2017). Interestingly, both of Alexander’s parents, his grandparents and an older sister are of normal height. Therefore, what do you think the mode of inheritance is for...

question 14 part 1 Tay-Sachs disease is lethal disorder caused by a recessive mutation, in this case at the TS locus in humans. TS/TS and TS/ts genotypes do not show symptoms of the disease; however, by the age of 6 months, ts/ts infants begin to regress, usually dying by the age of five. No cure is known for Tay-Sachs. Tay-Sachs most commonly strikes people from relatively small, closed societies, specifically those of eastern European Jewish (Ashkenazy Jews) and Louisiana (US)...
