The objective of this study was to analyze the correlation between Holstein body conformation traits and milk production traits in the Shanghai region. In total, 871 Holstein cows were randomly chosen from 28 dairy farms in Shanghai at second stage of lactation as the object of our study. Five milk production traits, including 305-d milk yield, butter fat percentage, milk protein percentage, pe...

Evaluation of essential oil yield, morphological and phenological traits of seven populations of twoChamomilespecies )Matricaria aurea and M. recutita), were carried out using Randomized Completely Blocks Design (RCBD) in three replications in Alborz research station in Karaj, Iran during 2011-2012. Data were collected for 12 morphological and phenological traits. Analysis of variance showed si...

the association between 140 microsatellite bands of 20 primer pairs and 13 quantitative traits recorded on 70 aegilops crassa from iran was evaluated. pearson’s coefficients showed significant correlations between some morphological traits. polymorphic information contents (pic) of loci were in the range of 0/16 (xgwm190) to 0/44 (xgwm161). the result of multiple regression analysis showed sign...

Abstract Misalignment between male and female interests over mating creates interlocus sexual conflict that is known to drive the coevolution of reproductive traits. Males females also share majority their genome, which may cause these traits be genetically covary sexes experience intralocus where beneficial alleles in one sex are costly when expressed other. Here, we use a quantitative genetic...
