I.4 Where the rare alleles are found
p is a gene A frequency, N is the number of individuals (genotype i.e. the number, so the number of genes is 2N , so all individual gene A number is 2NP ), p party is of PAA , NP2 is: genotype AA number of individuals, so that all genotypes AA gene of an individual a number is 2pn2 ; obtained:
The ratio is a whole A gene in AA content in homozygous genotype, is P (typically the minimum value), as in the hybrid . 1-P .
and so:
Because the gene is called the low frequency genes rare genes, i.e. p is very small, that is the gene homozygous genotype probability is extremely small. The common gene frequency gene is large, that is a high probability in the homozygous genotypes.
