    Study Notes

    Population Genetics: A Concise Guide

    • John H. Gillespie authored the book "Population Genetics: A Concise Guide"
    • The book offers a condensed overview of population genetics, focusing on key concepts and principles.
    • It is praised for offering clear and original derivations, filling gaps in the previous edition.
    • James F. Crow, author of "Genetics Notes", commends its ability to simplify a complex subject without distorting its essence.

    Linkage Disequilibrium

    • This term describes the associations of alleles located on chromosomes.
    • This concept is particularly important in understanding the dynamics of gametes, especially when considering random mating and recombination.
    • The simplest model demonstrating linkage disequilibrium is a diploid species with two linked loci, each with two segregating alleles.
    • The probability of a recombinant gamete occurring at meiosis is denoted by the recombination rate (r).
    • This is also known as the genetic or map distance between the loci which is always greater than r because it corresponds to the average number of recombinational events rather than the probability of a recombinant offspring.
