Abstract :
To study the genetic polymorphism of κ-casein (
) gene as candidate gene for marker-assisted
selection in different
domestic livestock species, blood samples were randomly withdrawn from
34 Alpine and 42 Saanen goats. DNA was extracted from blood samples and a 416 bp fragment
from exon 4 of the CSN3 gene was amplified by polymerase chain reaction (PCR). PCR products
were analysed using single strand conformation polymorphism (SSCP) method. Results indicated
that there were two (K
and K
) conformational patterns with frequencies 0.91 and 0.09 for Alpine
and 0.76 and 0.24 for Saanen goats, respectively. A Chi-square test confirmed Hardy-Weinberg
equilibrium for the gene in both breeds.
