Plant height is a complex trait
determined by many genes with small effects (Alheit et al.
Ultrasonic measurement is generally used for in vivo intramuscular fat content, back and flesh, back-fat thickness, loin eye area, buttocks fat thickness traits; As a complex trait
, meat quality is usually graded by various indicators, such as muscle color score, tenderness, intramuscular fat content, marbling, fat color score, line or dripping water loss, carcass level, pH, flavor and other indicators(Doran et al.
This wide range suggests that oxalate concentration is a complex trait
controlled by multiple genes, each with a small effect among the tested spinach varieties.
For height more than any other complex trait
, scientists have made a Herculean effort.
Drought resistanceis it really a complex trait
2012) is involved in addiction to many drugs, the dopamine-receptor encoding gene, D2DR, has been strongly implicated in a complex trait
referred to as "reward deficiency syndrome" (Blum et al.
As the costs associated with validating a given gene's role in driving a complex trait
are considerable, an effective strategy for prioritizing candidate genes is crucial.
For a proper estimation of honey quantity, which is a complex trait
, there were taken in consideration, besides productivity parameter and reproduction index (queens prolificness, developing of nest brood), the precocity of developing the bee colony at the beginning of the keeping season, family resistance to the winter season, diseases resistance, and behaviour index (aggressiveness/ gentleness, tendency of swarming, running on the honeycomb, etc.
Consider a complex trait
controlled by 100 QTL and with a low heritability (H = 0.
The company's products provide practitioners of genomics-based medicine and forensics with a comprehensive system for complex trait
dissection and patient/subject classification.
Bressan points out that scientists have always assumed the ability to thrive through stress was a genetically complex trait
, so researchers believed it would be a waste of time to try to create new varieties.
As yield is a complex trait
depending on successful completion of different steps of reproductive organ development, including flower differentiation and efficient flower fertilization,TomGEM will use trans-disciplinary approaches to investigate the impact of high temperature on these developmental processes.
