1.0 Quantities in population genetics

The genetics of populations deals with frequencies of genes and genotypes in populations and factors which can modify them such as selection, inbreeding and crossbreeding. Genes are assumed to be located at a locus on a chromosome. The locus may have several alleles which represent different forms of the gene at the locus.

Of particular importance for this course are a few quantities that we will revisit at different levels. It is important for you to become familiar with these quantities:

Allele frequency

Genotype frequency

Variance

Linkage disequilibrium

Expected heterozygosity/homozygosity

Quarterly Results
