Perhaps you are a fan of the PowerBall Lottery Game. We often have our favorite numbers and daydream about how we would spend our winnings. You may be glad to know that you have already won a lottery - when you were conceived. You have some characteristics of both parents - but also characteristics which seem to be uniquely yours. How does the idea of a lottery apply to your genetic makeup and its expression? In what way? Or does it apply?

You could say that the traits that you inherited from your parents were like winning the lottery if you are really pleased with your attributes. When you were created it was from a sperm and an egg from your father and mother, respectively, that randomly contained half of their chromosomal compliment. Humans have 46 chromosomes or 2x23 (2N where N= 23) because each of the 23 chromosomes has a compliment. During the formation of egg and sperm cells a 2N germ ...

  • Mendel's 2nd Principle

    Conclusion: The law of independent assortment state that, "During gamete formation, the segregation of the alleles of one allelic pair is independent of the segregation of the alleles of another allelic pair" (2).

  • Genetic frequency

    That means that the allelic frequency is the square root of 11% = 33%.

  • Mendel Second Genetic Law

    Mendel's Second Law of independent assortment which states that "during gamete formation the segregation of the alleles of one allelic pair is independent of the segregation of the alleles of another allelic pair" does not hold true all the time.

  • How to calculate gene / allele frequency & relative fitness

    Hence frequency of allele B after one generation : p2 + 2pq : (0.75)2 + 2 * 0.75 * 0.25 = 0.9375 In Hardy-Weinberg population, allelic frequency can be calculated if the initial frequency of the gene is known.

  • Explanation for deviation from Hardy-Weinberg Equilibrium

    No change in allelic frequency due to mutation: A population will be at Hardy-Weinberg equilibrium, only when there is no change in allelic frequency due to mutation.

  • Population-Genetics Problems using Hardy-Weinberg Equilibrium.

    The allelic frequency of CR is 140/200 = 0.7 The allelic frequency of Cr is 60/200 = 0.3 (Note that the frequency of the two alleles adds up to 1 - 0.7 + 0.3 = 1). 3) The expression p + q = 1.

  • Genetics and Population Biology

    If the migrating individuals stay and mate with individuals in their population, they can provide an influx of alleles which can alter the allelic frequency.

  • Population Genetics

    Therefore the allele frequencies are (where p = frequency of R and q = frequency of r): p^2= 0.292 -> p= 54.0% (take the square root of 0.292 to get 0.54) q^2= 0.268 -> q= 51.8% Note that p+q does not = 1.

  • Hardy-Weinberg Problem

    determining allelic frequency and arrive at the solution.
