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.
