Summary
Understanding meat tenderness requires knowledge of genetic and environmental factors. Controlling daily variations is key for the livestock industry to consistently produce tender meat.
Area of Science:
- Animal Science
- Meat Science
- Genetics
Background:
- Meat quality, particularly tenderness, is crucial for livestock industries.
- Tenderness is influenced by connective tissue, sarcomere length, proteolysis, intramuscular fat, and energy metabolism.
- Genetic and environmental factors interact to affect meat tenderness.
Purpose of the Study:
- To provide an overview of meat tenderness.
- To explore the influence of genetics on meat tenderness.
- To examine genotype-environment interactions affecting meat quality.
Main Methods:
- Review of scientific literature on meat tenderness.
- Analysis of genetic factors influencing meat traits.
- Examination of environmental impacts on meat quality.
Main Results:
- Specific genes (myostatin, callipyge, Carwell, calpain system) impact meat tenderness.
- Interactions between production/processing environments and genetics are evident in sheep and cattle.
- Significant day-to-day variation in tenderness necessitates control measures.
Conclusions:
- Consistent production of tender meat requires understanding genetic predispositions and environmental influences.
- Managing variability in meat tenderness is essential for industry success.
- Further research into genotype-environment interactions can optimize meat production.

02:27Background and Environment Affect Phenotype
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

01:20Gene-Environment Interactions
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...
01:28Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

01:28Causes of Social Behavior III: Biological and Environmental Influences
Social behavior is a complex phenomenon that arises from the interaction between biological predispositions and environmental influences. This intricate interplay shapes how individuals think, feel, and act in various social contexts. Understanding these mechanisms requires insights from psychology, neuroscience, genetics, and evolutionary theory.Environmental Influences on Social BehaviorEnvironmental factors, including temperature, odors, and visual stimuli, play a crucial role in shaping...
01:06Heritability
Heritability is a statistical concept that measures the degree to which genetic differences among individuals contribute to trait variations within a population. It is a fundamental idea in genetics, often prone to misinterpretation. Heritability is expressed as a percentage, reflecting the proportion of variation in a specific trait across a population that can be linked to genetic differences. However, it's important to understand that heritability does not determine how "genetic" a trait is,...
01:37Epigenetic Regulation
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
