A total of 500 local chickens from different regions Iraq, which were divided into five groups according to the they taken, namely, East (E), West (W), North (N), South (S), and Central (C) Iraq. The blood samples collected tubes containing an EDTA, DNA extraction was carried. Using 20 primers Gen Script USA, random amplification polymorphic (RAPD-PCR) carried out. reaction PCR had a final volu...

The success of genomic selection mainly depends on the extent of linkage disequilibrium (LD) between markers and quantitative trait loci (QTL), number of QTL and heritability (h2) of the traits. The extent of LD depends on the genetic structure of the population and marker density. This study was conducted to determine the effects of marker density, level of heritability, number of QTL, and to ...

objective: flowering time (ft) in cereals controlled by genes that had a main factor on plant development. methods: genetic and phenotypic diversity of four flowering time genes (ft2, ft3, ft4, ppd-h1) in 19 genotypes of cultivated and wild barley was evaluated and a total of 107 alleles were amplified. genotypes based on days to flowering time and molecular data were grouped into early, middle...

Genetic diversity in perennial Salvia judaica Boiss (Judean sage) and palaestina Benth (Palestinian species using touch-up directed amplification of minisatellite region DNA (TU-DAMD) has been performed two separated sets; the first set (set A) initial annealing temperature was increased from 50 °C to 55 °C, whereas, second one B), it 60 by 0.5 °C/cycle during 10 PCR cycles. Fifteen DAMD primer...
