  • Model Of Inheritance In Fruit Flies

    1105 Words  | 3 Pages

    Multiple allele is when more that one allele is being crossed and all of the traits are being crossed together. Sex linked inheritance is when the gene for a certain trait is carried on either the X or Y chromosomes for the parent. The goal of this lab is to better understand genetics. The guiding question is, Which model of inheritance best explains how a specific

    1165 Words  | 3 Pages

    Retinitis pigmentosa is a genetic disorder that causes blindness in the people that are affected by it. I chose retinitis pigmentosa because my grandmother has this genetic disorder. The disorder is very costly on those who have it. The disorder has robbed my grandmother of the life she wanted. She is no longer able to do the things she once was. She is legally blind, cannot drive, and has trouble getting around crowded areas. Retinitis pigmentosa was discovered by Doctor Donders in 1857. Retinitis

    this type of hearing loss, along with others that are prenatal or present at birth. Fifty percent of congenital hearing incidents in children are all caused by genetic factors. These may be autosomal dominant, autosomal recessive, or related to the sex chromosome X. When one parent carries a dominant gene for hearing loss or has hearing loss, this means that they have the autosomal dominant gene for it... ... middle of paper ... ...n the treatment process because this is the primary way to get

  • What Is Pompe Disease?

    1262 Words  | 3 Pages

    What is Pompe Disease? Pompe disease is a genetic disorder which deals with a mutation within a gene called the GAA gene, glucosidase, alpha; acid, and produces an enzyme to produce a buildup of glycogen, a complex sugar, within body cells which cause the lysosomes to not reuse the sugar properly. The name of this enzyme is called alpha-glucosidase, more commonly known as acid maltase. The GAA gene is located on Chromosome 17 on the q arm between the positions 25.2 and 25.3 (GAA, paragraph 4)

  • Apterous Experiment

    1326 Words  | 3 Pages

    to understand how traits are passed from one generation to the other as well as understanding the difference between sex linked and autosomal genes. One particular trait that is observed in this experiment is when a fly is lacking wings, also known as an apterous mutation. In this experiment, we will determine whether this mutation is carried on an autosomal chromosome or on a sex chromosome. The data for this experiment will be determined statistically with the aid of a chi-square. If the trait

    patterns of inheritance in the eye color and the wings. The wild type flies had red eyes and full wings, while the mutant phenotype had brown eyes and no wings. We also had to study the sexes of the flies. The male flies had darker abdominal tips and sex combs on both of their forearms. For the results, my group had predicted as follows: X-linked X= dominant allele X’= recessive allele XX x XY X-linked Dominant This would produce 100% of the dominant phenotype in females. This would

  • Duchenne Muscular Dystrophy Research Paper

    There are many diseases in the world, some you are born with others you just happen to get. There are some diseases that just happen to males and some diseases just happen to females. One of the diseases you could be born with if you are male is called Duchenne Muscular Dystrophy. This type of disease is serious for the males with this condition. A French neurologist named Gulliaume Benjamin AmandDuchenne. Guillaume is best known for his research on nerves and muscles. He studied medicine in Paris

  • Genetics In Offspring

    parent to child through generations. Genetics are passed down through chromosomes in DNA which are located in every cell of the body. Each cell contains 46 chromosomes (23 pairs) including the X and Y chromosomes. The only exception to this are the sex cells (sperm and egg) which have 23 chromosomes. Each chromosome carries genes for a certain trait which will be inherited to the offspring. When a new organism is fertilised through intercourse, the 23 chromosomes from the father’s sperm combine with

    unite during fertilization and is carried by every individual. The Law of Independent Assortment states that each parent randomly passes on alleles to their offspring. Although, the Law of Independent assortment does not take in account the patters of sex-linked inheritance. The Drosophila live a distinct four-staged life cycle that requires approximately two weeks to reach complete maturity2. The stages are known as egg, larval, pupa, and adult. The egg is a small oval shape, and can barely be seen

  • The Effects of Temperature on Crossing Over Frequency

    1888 Words  | 4 Pages

    According to the results obtained in the laboratory exercise, it appears that the gene to centromere distance tends to vary at different temperatures, as well as with different environmental conditions. At different environmental conditions, variations in recombination frequencies are found in Sordaria . Recombination generates new combinations of existing genetic variation and therefore may be important in adaptation and evolution ( Saleem2001). Throughout the years it has been observe how different

    diseases. They are also essential to linkage analysis. Linkage analysis is the analysis of the linkage in the inheritance between genes at different loci based on the observational phenotypes and the known pedigree structure (Palmer, 2011). Linkage between loci is the tendency for alleles of two or more loci close on the chromosome to be transmitted to the next generation together. So generally the closer two genes lie on a chromosome, the more likely they will show linkage. Genes located on different chromosomes

  • Sex And Recombination Essay

    1106 Words  | 3 Pages

    4. Sex has been around for millions of years, transferring, spreading and exchanging genes from offspring to offspring either asexually or sexually. Although, many species are specific with whom or what they mate with and they also consider the consequences of mating. Sex can have advantages and disadvantages that could lead to offspring or to death. The advantage of sex is recombination. Although, recombination can be broken down into many parts. Recombination created genetic variation leading to

    activity, as opposed to what it primarily consists of, namely, possessing a set of minor and frequently unreliable organs"(xi). You will become convinced that the title should not be "Complete Guide to Guys," but "More Reasons Why Women Are The Better Sex." In fact, Barry himself seems to support the latter idea through his discussion of "the Punch Reflex," "the Noogie Gene," scientific reasons as to why guys act like jerks, the hidden truth of the Space Shuttle program, and standards. Yes, guys are

    Battle of the Sexes Tiny pink nipples peeked out from our pasty chests and our protruding ribs gave way to our sun-starved tummies. Alex and I ran free, our shirts flapping in the wind as we waved them over our heads like victory flags. Moments later, on that April day in first grade, my best friend and I experienced the injustices of womanhood; our teachers informed us that we were not allowed to go shirtless during recess. "Why?" Alex whined. "That's not fair," I protested. "The boys can
