Voles were trapped in fields in southern Indiana and genotyped for a transferrin

Question

Voles were trapped in fields in southern Indiana and genotyped for a transferrin locus. The following numbers of genotypes were recorded, where Te and Tf represent different alleles.

TeTe - 407; TeTf - 170; TfTf - 17

Calculate the genotypic and allelic frequencies of the transferrin locus for this population
.

2 apts) voes (Morotus ochrogasfery were trapped selds in where genotyped or a tansferrin loads. The following numbers of genotypes were recorded, and TF represent different alleles. THE TE e the genotypic and alelic frequencies of the transferrin locus for this papulation

Explanation / Answer

TeTe= 407

Te Tf=170

TfTf=17

Total =407+170+17=594

Genotypic frequency:

TeTe=( 407/594 ) * 100= 68.51 %

TeTf=(170/594) *100= 28.61%

TfTf= (17/594) *100= 2.86 %

Allelic frequency:

The analyzed population has two alleles therefore total alleles= 594 *2 = 1188

Frequency of Te allele = [( 2*407) +170]/1188 = 0.83

Frequency of Tf allele= [( 2* 17) + 170]/1188= 0.17
