Temka [501]

The great plains states and parts of the upper Midwest are collectively referred to as Tornado Alley due to the number of these severe weather events that occur each year.

The term Tornado Alley was framed in 1952 by U.S. Air Force meteorologists Captain Robert C. Miller and Major Ernest J. Fawbush. Tornado Alley is generally associated with the corridor-shaped region in the Midwestern United States where tornadoes commonly occur.

It typically includes regions of Texas, Oklahoma, Kansas, Nebraska, South Dakota, Indiana, Missouri, Iowa, Illinois, and Ohio. These states together with the state of Florida, are some of the parts of the US that are highly susceptible to tornadoes, nevertheless, tornadoes have been recorded in all the fifty states.

A high heritability coefficient can result when the trait ________ across individuals or when genes are important in a(n) ______
klemol [59]

A high heritability coefficient can result when the trait varies greatly across individuals or when genes are important in an absolute sense.

What is heritability coefficient ?

The degree to which genetic variations among persons may adequately explain the variations in their attributes is known as heritability. Heritability, which is denoted by the statistic h2 in science, describes the proportion of a trait's variation that can be attributable to genetic variation. An estimation of a trait's heritability is particular to one population in a particular setting, and it might alter over time as conditions change.

Estimates of heritability range from 0 to 1. When a variable's heritability is near to zero, it means that environmental influences, rather than genetic differences, account for the majority of a person's variation in that trait. A heritability that is close to one means that genetic differences account for practically all of the variability in a trait and that environmental influences have a negligible role.
