Abstract

The study aimed at determining the qualitative traits and genotypic and allelic frequencies of prolactin gene polymorphism in
Normal (NF) and Frizzle feathered (FF) chickens. Blood was collected and released on a Fast Technology Analysis (FTA) paper
gotten from Federal University of Agriculture, Abeokuta. Three plumage colours were observed through visual appraisal which
are multi-coloured, white and black. Frequency and percentage of each colour were obtained. The frequency and percentage of
each colour in the NF chicken were multi-coloured (48 and 92.31%), white (3 and 5.77%) and black (1 and 5.77%), respectively.
No appearance of white colour was seen in FF chicken; however, the frequency and percentage of black were 1 and 1.25% while
multi-coloured were 7 and 87.5%, respectively. Three genotypes were observed including II, ID and DD which consequently had
two alleles I and D during gel electrophoresis using agarose gel after specific primers have been amplified using PCR machine.
The results of the present study showed the presence of polymorphism for the prolactin (PRL) gene which shows two alleles and
genotype; I, D and ID respectively in FF chicken and two alleles (I and D) and three genotypes (II, DD and ID) in NF chicken.
Conclusively, prolactin gene can be used as a marker in the genetic improvement of Nigerian indigenous chickens due to the presence of polymorphism.
