Evaluation of Genetic Variability in a Breeder Flock of Native Chicken Based on Randomly Amplified Polymorphic DNA Markers
A study was undertaken to evaluate the genetic variation in the 10th generation of a breeder flock of native breed selected for high egg and meat production in native fowls breeding station, Mazandaran, Iran. Venous blood samples were collected from 100 birds of both sexes. The RAPD-PCR technique was applied to generate a DNA fingerprint of individuals. Initially, a total of 20 ten-nucleotide a...

متن کاملEstimating Genetic Parameters of Body Weight Traits in Kourdi Sheep
For estimating genetic parameters for body weight traits in Kourdi sheep data were collected from 1996 to 2013 in Kourdi Breeding Station in Northern Khorasan province of Iran. Studied traits were birth weight (BW), weaning weight (WW), six-month weight (6MW), nine-month weight (9MW) and yearling weight (YW). The fixed effects in the model were lambing year, sex, type of birth and age of dam. (...
متن کاملVariance Component Quantitative Trait Locus Analysis for Body Weight Traits in Purebred Korean Native Chicken.
Quantitative trait locus (QTL) is a particular region of the genome containing one or more genes associated with economically important quantitative traits. This study was conducted to identify QTL regions for body weight and growth traits in purebred Korean native chicken (KNC). F1 samples (n = 595) were genotyped using 127 microsatellite markers and 8 single nucleotide polymorphisms that cove...
