DNA‚ the chemical that makes up our genes‚ contains a "code" of three letter words known as "codons" or "trinucleotide repeats." Many genes normally contain a trinucleotide repeat‚ which is present several times. When the number of repeats increases to a larger than normal number of copies‚ the DNA is altered‚ and the gene may not function correctly or at all ("Trinucleotide repeats: fragile-x‚" 2008). Huntington’s Disease (HD) is an autosomal dominant pattern of inheritance. Males and females

Genetics & Drosophila Melanogaster Lab Report Background: For two months‚ you will breed Drosphila melanogaster (fruit flies) and set up genetic crosses in order to determine the pattern of inheritance of certain mutant traits. The traits for which we will examine the pattern of inheritance are apterous (wingless)‚ vestigial (crippled wings) or white eyes. These are all mutant strains. The normal condition (winged and red eyes) is referred to as the wild type strain. Objective: The intial

PROBABILITY and MENDELIAN GENETICS LAB Hypothesis: If we toss the coin(s) for many times‚ then we will have more chances to reach the prediction that we expect based on the principle of probability. Results: As for part 1: probability of the occurrence of a single event‚ the deviation of heads and tails of 20 tosses is zero‚ which means that the possibility of heads and tails is ten to ten‚ which means equally chances. The deviation of heads and tails of 30 tosses is 4‚ which means that the

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

Cystic Fibrosis: Description‚ signs and symptoms: Cystic fibrosis is a genetic disorder‚ which is acquired at conception and therefore present at birth. The disorder is entirely caused by one pair of genes. People with cystic fibrosis produce abnormally thick‚ stick mucus in the linings of internal organs such as the lungs and intestines. The most common signs are persistent coughing‚ excessive sweating leading to salty skin‚ huge appetite but poor weight gain‚ and pale‚ oily‚ very smelly faeces

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
