In the present investigation, Principal Component Analysis (PCA) was applied to various variables to describe meat quality. Sixteen meat quality variables were examined, and the analysis showed that 60.71% of the total variation was explained by the first three principal components. L, a, b as colour data; odour, tenderness, flavour, acceptability as sensorial traits; hardness and chewiness as ...

production of high yielding hybrid cultivars is among the main objectives of breeding programs in sunflower and on evaluation of the combining ability of the inbred lines necessary to select for the appropriate parental lines for production of hybrid cultivars. this study was conducted to investigate the general and specific combining ability and the mode of inheritance for agronomic and seed q...

Endosperm traits are trisomic inheritant and are of great economic importance because they are usually directly related to grain quality. Mapping for quantitative trait loci (QTL) underlying endosperm traits can provide an efficient way to genetically improve grain quality. As the traditional QTL mapping methods (diploid methods) are usually designed for traits under diploid control, they are n...

A sample of 6- to 13-year-old clinic-referred (n = 136) and volunteer (n = 30) participants was investigated for a potential interaction between the quality of parenting that a child receives and callous-unemotional traits in the child for predicting conduct problems. Ineffective parenting was associated with conduct problems only in children without significant levels of callous (e.g. lack of ...

UNLABELLED Numerous studies show that changes occurring in a woman's organism during menopause may lower her quality of life. This study involved 630 healthy postmenopausal women from Poland. Its purpose was to assess their quality of life in relation to socio-demographic variables, medical data and personality profiles. The authors used the Short Form Health Survey (SF-36) to assess quality of...

The aim of this study was to investigate the genetic and phenotypic correlations of egg quality traits in Khazak chicken. Albumen height (AH), albumen weight (AW), eggshell color (ESC), yolk color (YC), eggshell index, long length of egg (ELL), short length of egg (ESL), eggshell weight (ESW), egg weight (EW), Haugh units, and yolk weight (YW) were measured in 201 eggs collected 6 d sequentiall...

Female choice can impose persistent directional selection on male sexually selected traits, yet such traits often exhibit high levels of phenotypic variation. One explanation for this paradox is that if sexually selected traits are costly, only the fittest males are able to acquire and allocate the resources required for their expression. Furthermore, because male condition is dependent on reso...

The Yangtze River Delta White Goat is the only goat breed that produces high-quality brush hair, or type III hair, which is specialized for use in top-grade writing brushes. There has been little research, especially molecular research, on the traits that result in high-quality brush hair in the Yangtze River Delta White Goat. To explore the molecular mechanisms of the formation of high-quality...

The study evaluated the body weight during growth (BWG), body weight at slaughter (BWS), breast meat yield (BMYg), percent breast meat yield (BMY) and breast meat quality (colour and drip loss) of genetically featherless (scsc) broilers compared to their feathered sibs under hot conditions. Two hundred featherless chicks and 200 feathered sibs were reared under hot conditions in two rooms (aver...
