Often, near- or far-sightedness will run in families. If one or both parents are visually impaired, their children are more likely to be visually impaired as well, although the intensities can vary -- one child might be very nearsighted, while another might not be as bad.

What is the difference between a genetically inherited vs a contagious disease?

A genetically inherited disease is passed down from parents to their offspring through genes, while a contagious disease is caused by pathogens such as bacteria or viruses that can be transmitted between individuals through direct or indirect contact. Genetically inherited diseases are not contagious and cannot be spread from person to person, whereas contagious diseases can be easily transmitted between individuals.


Does a person learn an inherited behavior?

No. Example: In birds, they have to LEARN how to fly, so that is a learned behavior. But, they already know how to build a nest, so that is an inherited behavior.


Slurred speech blurred vision and impaired judgment are the results of?

Slurred speech, blurred vision, and impaired judgment are common symptoms of alcohol intoxication. Alcohol affects the central nervous system, slowing down brain function and coordination, leading to these effects. It can be dangerous and increase the risk of accidents or injuries.


What must be true of traits that are passed down through generations?

Traits that are passed down through the generations must be either culturally or environmentally inculcated or genetically inherited (or some combination of these). Evolutionary biology concerns itself with genetically inherited traits. In the long term, for genetically inherited traits to continue to be passed down through the generations, they must be at least neutral with regard to reproductive fitness, or advantageous (i.e. they must not be subject to negative selection pressure)


WHen you are fatigued your peripheral vision?

can become impaired, leading to a decrease in awareness of your surroundings. This can make it more difficult to react to objects or movements on the periphery of your vision, increasing the risk of accidents or injuries. It is important to take breaks and rest when feeling fatigued to avoid these potential negative effects on your peripheral vision.
