Study of transferrin polymorphism in a population of Carp (Cyprinus carpio)‎

الملخص EN

This study was carried out at the college of agriculture, Basrah university.

Fifty blood samples taken from carp (Cyprinus carpio) analyzed by Polyacrylamide gel electrophoresis (PAGE) under alkaline conditions at pH 9.8.

The present study is aimed to provide the first insight into the genetic constitution of carp based upon analysis of Transferrin.

Five genetic types of transferrin were revealed (Tf1Tf1, Tf2Tf2, Tf5Tf5, Tf3Tf2 and Tf1Tf5) in Carp controlled by four allelic genes of that locus (Tf1, Tf2, Tf3 and Tf5).

These fractions are controlled by co dominant autosomal genes according to the Mendelian laws of inheritance.

Differences in gene frequencies between alleles were observed.

The gene frequencies of Tf1, Tf2, Tf3 and Tf5 were 0.15, 0.51, 0.29 and 0.05, respectively.

The predominant genotype was Tf2Tf2 (44%) then Tf3Tf3 (22%).

Transferrin was identified as highly polymorphic protein markers which is a result of importance for future genetic characterization of the carp .
