Genetic polymorphisms in Iranian native poultry breeds Part III. Albumin and transferrin polymorphisms

Abstract

Albumin and transferrin polymorphisms were studied in five Iranian native chicken breeds maintained in genetic reserve Dashtyary, Lary, Marandy, Naked neck and Common breed. The frequency of albumin allele A is very low or non-existent in the breeds ranging from 0.000 to 0.031. B allele is very frequent ranging 0.917 to 0.960 and the frequency of C allele ranges between 0.020 to 0.016. The frequencies of transferrin allele A vary between breeds from 0.016 to 0.075, B has a frequency range of 0.355 to 0.523 and C allele is characterised by frequencies from 0.522 to 0.629. The heterozygosity index for transferrin regarding all breeds lies within the range of 0.478 to 0.559 and for albumin 0,077 to 0.155. The accuracy to distinguish individual chickens taking random samples is very low for albumin PD<0.27 in all breeds the accuracy is higher for transferrin PD<0.27.
