Answer:
A polygenic trait can be described as a physical trait which is influenced by more than one gene.
The three types of selection for a polygenic trait are:
1) Directional Selection: In a directional selection, one of the phenotype is favored in an ecosystem. As a result of this favoring, the allelic frequency changes and shifts in favor of this particular trait.
2) Stabilizing selection: It is a type of natural selection in which the intermediate trait is favored. The population carries a middle trait in abundance.
3) Disruptive Selection: Disruptive trait is a type of natural selection in which the traits on the extreme sides are favored. The intermediate traits are less favored.
Wavelength light source is part of the control group for William’s experiment
<u>Explanation:</u>
Sir William wanted to conduct an experiment to observe how much heat passed through different colour filters of the sunlight. He directed sunlight to pass through the prism and observed vibgyor and measured the temperature. He found that the temperature increased from violet to red.
Then he was inquisitive to find the temperature beyond the red ray. That’s when he found the infrared rays which had higher temperature that was not to be seen through naked eyes. He performed experiments using the light source and found that the wavelength of light are not refracted in a particular pattern.
