Eye color is not an example of polygenetic traits. Skin color is.

Eye color is rather simple as far as genetics go (in humans).

Brown (B) is dominate and blue (b) is recessive. A person with blue eyes has to have to have both genes for the color blue (bb). A person with brown eye color can has both genes for brown (BB) or one for brown and one for blue (Bb). The blue is not expressed in this case with Bb. Some people have hazel eyes but this is a variation of the blue color.

What kind of trait is present when many different genes are control a single trait such as skin color?

The trait described is known as a polygenic trait. Polygenic traits are controlled by multiple genes, each contributing to the overall phenotype, leading to a continuous range of variation. Skin color is a classic example, as it results from the interaction of several genes, resulting in a spectrum of shades rather than distinct categories. This complexity often reflects the influence of both genetic and environmental factors.


What are polygentic traits?

Polygenic traits are those that are controlled by multiple genes, with each gene contributing a small amount to the phenotype. These traits often exhibit a continuous range of variation due to the additive effects of the multiple genes involved. Examples include height, skin color, and intelligence.


What is shot variation?

Shot variation refers to the ability of a player to hit different types of shots during a game, such as forehands, backhands, volleys, drop shots, and lobs. Having good shot variation helps to keep opponents off balance and can be used strategically to control and win points during a match.


What are causes of variation in quality?

Causes of variation in quality can include differences in raw materials, production processes, equipment maintenance, employee training, and quality control measures. Variations in these factors can result in inconsistencies in product quality.


What is analytical variation?

Analytical variation refers to the differences in measurements or results that arise from the analytical process itself, rather than from the sample being tested. This variation can be due to factors such as instrument calibration, the method of analysis, reagent quality, or environmental conditions. It is important to minimize analytical variation to ensure accurate and reproducible results in scientific experiments and quality control processes. Understanding and controlling this variation is crucial for achieving reliable data in research and industrial applications.

If Several genes control human eye color. Because of this eye color shows a continuous variation from very dark brown to green to blue. What is this an example of?

This is an example of polygenic inheritance, where multiple genes contribute to a single trait, resulting in a continuous range of phenotypes. In the case of eye color, several genes interact to produce varying levels of melanin, leading to the spectrum of colors observed from dark brown to green to blue. This type of inheritance often results in quantitative traits, which exhibit continuous variation rather than distinct categories.

What is Continuous control?

A continuous control system is design and built to perform one manufacturing task, 24 hours a day, 7 days a week, with some time required for system maintenance. An example of a continuous control system is a car assembly line.


What is the purpose of statistical process control?

to check the process variation.


Why do you convert s domain to z domain in control system?

Because most modern control systems are implemented using digital hardware, which is exists in discrete (z), not continuous (s), space.


What is a type of variation outside predicted control limits called?

A type of variation outside predicted control limits is called "special cause variation" or "assignable cause variation." This variation indicates that there is an unusual or non-random factor affecting the process, which can be investigated and addressed. In contrast to common cause variation, which is inherent to the process, special cause variation signals that something specific has disrupted the system. Identifying and eliminating these special causes is essential for maintaining process stability and quality.

What are the advantages of statistical process control?

It detects the presence of special causes of variation.


How can the variation of excitation of an alternator be used to control power factor?

When a generator is connected to a load it is never going to be perfectly matched because of its inductance, when you have inductance the current starts to lag.
