Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

3. A woman has a rare abnormality of the eyelids called ptosis, which makes it impossible for her to open her eyes completely. The condition has been found to depend on a single dominant gene (P). The woman's father had ptosis, but her mother had normal eyelids. Her father's mother had normal eyelids. a. What are the probable genotypes of the woman, her father, and her mother? b. What percentage of her children will be expected to have ptosis if she marries a man with normal eyelids?
4. Marfan syndrome is a genetic trait caused by in a dominant allele. The trait causes a weakening of the aorta that can be fatal. A teenager whose mother has the syndrome (but whose maternal grandfather was not affected), and whose father was unaffected, is concerend that she may have the trait. a. What is the phenotype of each of her parents? Genotype? b. What is the chance that the teenager has Marfan syndrome?
1. The first genetic test used a short DNA sequence that was closely linked to the Huntington’s locus. People taking the test were classified as to whether they had the DNA sequence that was linked to the Huntington’s disease. This method was 95% accurate. This means that 95% of the people who had the Huntington’s-linked DNA sequence actually inherited the Huntington allele. It also meant that 95% of the people who did not have the DNA sequence linked to the Huntington allele did not inherited the wild-type allele (not the Huntington allele).Why might this preliminary test not be as accurate as a gene test for the actual Huntington’s allele? Explain.

1. Can a test determine an individual's biological sex? And can testosterone produced by an athlete's own body provide an unfair advantage? 2. At the bottom of the section on development is a graph showing testosterone levels for male and female athletes. Most female athletes have less than 5 nm/L of testosterone, but a few have as high as 30 nmol/L which is above the average for male athletes. Which genetic condition(s) can cause XX individuals to have high testosterone levels? (3) The AR gene codes for a transcription factor which is only functional when testosterone is present. Based on what you know about transcription factors and about sex determination explain (A) Why do XY individuals with a mutation in the AR gene develop as females despite having male levels of testosterone? (B) Would you expect such individuals to be more muscular than an average female? (4) Do the case studies for the sprinter and the swimmer. Should they be eligible to compete? Explain your answer.
