Darwin [1], used morphological characters or polygenic traits to describe the hierarchy in complexity among related and distant species although he was unaware of the source of variation. Only later, after the discovery of Mendel’s laws explained that the genetic variations are generated by mutations. Speciation is based on the analysis of the extent of similarity among a wide variety of morpho...

The objective of this study was to determine the extent of variation in, and relationships among, biochemical and palatability traits within and among 11 major beef muscles. Longissimus thoracis et lumborum (LD), psoas major (PM), gluteus medius (GM), semimembranosus (SM), adductor (AD), biceps femoris (BF), semitendinosus (ST), rectus femoris (RF), triceps brachii (TB), infraspinatus (IS), and...

Efficient selection for specific culinary and nutritional quality traits needs a better understanding of the genetic and environmental control of quality traits at the structural, physiological and biochemical levels. Field experiments indicate great variability in the Phaseolus gene pool regarding the content of antinutritional compounds, as well as in cooking characteristics of the seeds. The...

This work was conducted to study the association of variations in VLDLR gene and mRNA expression liver ovary local Iraqi hens with some productive blood traits. The were studied using samples 173 pedigreed hens, 47 weeks old while tissue 30 60 old. Genotypic allelic frequencies, production traits, biochemical serum investigated. results showed that genotypic frequencies chickens did not agree H...

vermicompost can improve physicochemical traits of soil having desirable effect on plant growth and development due to its structural traits and having macro and micro nutrients, plant growth regulators and favorable microorganisms. in order to investigate the effect of interactions between ratios of vermicompost and saline stress on some morphological, physiological and biochemical traits of p...

Abstract Wild cherry ( Prunus avium L.) is a multi-purpose tree species with great ecological and economic importance for European forestry. Evaluating this phenotypic diversity quantitative traits characterization of to define its genetic resources conservation breeding strategies. In work, variations physiological, biochemical, anatomical morphological one-year-old wild seedlings were evaluat...
