Hello Mr. and Mrs. Jones. I would like to let you know that if you do have a baby‚ you are risking him or her having Sickle Cell Disease. What this is is it’s a disease that is genetically inherited and it involves the red blood cells. Mutations in the HBB gene cause this disease. This disease is inherited in an autosomal recessive pattern‚ which means both copies of the gene in each cell will have mutations. The parents of offspring with an autosomal recessive gene each carry one copy of the

Each cell in body contains nucleus which contains DNA. DNA is organized into long strands called chromosomes. Chromosome is made up of smaller units of DNA that is genes. Genes carry information on biological development of the body. Set of Chromosomes number: 23 pairs of chromosomes for each species

IB204 Mock exam 1 1) Tightly curled or wooly hair is caused by a dominant gene in humans. If a heterozygous curly-haired person marries a person with straight hair‚ what fraction of their offspring would be expected to have straight hair? A) 1/2 straight B) 1/4 curly C) 100% straight D) 3/4 curly E) It is impossible to predict the outcome. 2) Assume that a black guinea pig crossed with an albino guinea pig produced 5 black offspring. When the albino was crossed with a second black one‚ 4

Albinism and how it Affects People What is albinism? Well‚ albinism is a genetic disorder in which your body can’t produce or properly use melanin. Melanin is a pigment that your body produces and can be found in the melanocytes. Albinism is also a recessive trait‚ so you must inherit two recessive genes‚ one from each parent. Albinism is caused (most commonly) by a mutation in TYR gene. This gene produces an enzyme‚ Tyrosinase‚ that is responsible for the synthesis of Melanin in the body and

General Information -Maple Syrup Urine disease is an inherited disorder in which the body does not and is unable to process certain protein building block called amino acids leucine‚ isoleucine‚ and valine. -To treat this disease the infected would have to have a protein-free diet. Fluids‚ sugars and possibly fats are given through a vein (IV). II. Nature of this Mutation -Symptoms of this

Hemochromatosis is a genetic disease in which there is too much iron that builds up in your body‚ this is referred to as an iron overload. Iron is an essential nutrient found in many foods but can be toxic to our bodies if we have to much. “Normally‚ humans absorb about 8-10% of the iron found in foods that they eat.” People with Hemochromatosis can absorb up to four times more iron than a normal human being. Since our bodies have no natural way to get rid of the extra iron‚ it gets stored in your

Mutations are various forms of changes in ones DNA’s structure or makeup. This abnormality can happen for various reasons such as chemical misuse‚ harmful viruses or environment factors. When a mutation occurs in ones genetic structure‚ there is often a push to find out what went wrong and if it was a onetime occurrence or a genetic abnormality that no one in the family knew about until the recent discovery. This genetic abnormality occurs when there is a dominant gene which comes from a parent

Case Study: I’m Looking Over a White-Striped Clover; A Case of Natural Selection Jelena Vukadin Part 1: Minnesota Habitat: The Minnesota habitat has cold winters and fairly warm summers. They do not receive much rain which therefore results in not having many herbivores in the population (not very many plants for them to eat). North Carolina Habitat: The North Carolina habitat has mild winters and very hot summers. They receive much more rain yearly which is why they have many more herbivores in
