Chapter 36, Problem 10WIO

In the 1930s. the population geneticist J.B.S. Haldane famously said, “I would lay down my life for two brothers or eight cousins.” What was he talking about?

.. Nowadays, newborn babies are required to be tested for phynylketonuria (PKU), an autosomal recessive genetic disorder. If untreated, individual homozygous for PKU suffer mental retardation. In a recent year, 4 PKU babies were detected out of 126,000 tested. Assuming Hardy-Weinberg conditions, what is the frequency of the PKU gene in this population (Give your answer in decimal number with 3 decimal places)?
The eugenic movement was created in the early 20th century by Sir Francis Galton. Its aim was to improve the genetic pool of the human population by selective breeding. One idea was to discourage individuals with Mendelian autosomal recessive diseases to have children. However, the fallacy of this idea is shown by the fact that recessive lethal alleles (that are never found in homozygosity) can persist in populations for hundreds to thousands of generations. Which one of the following statements best explains the persistence of those alleles in populations?     There is heterozygote advantage in those populations.     Recessive alleles keep being produced by mutation.     Recessive alleles cannot be selected against when present in heterozygotes.     Genetic drift keeps recessive alleles at a relative high frequency in populations.     Consider the action of mutation and of genetic drift in a population. What do you expect genetic variation will be in a…
CANDY GENETICS: A college student studying genetics has hypothesized that Tavorite type of candy is a genetically inherited trait and thus, 75% of people will prefer Hershey's; 10% Twix; 10% Nerds; and 5% Sour Patch Kids. After tabulating his findings, his data is as follows... 720 prefer Hershey's: 98 prefer Twix; 112 prefer Nerds; and 70 prefer Sour Patch Kids. Statistically, you want to know if his data supports his hypothesis (A) State the null hypothesis.
