frequency is 100 percent, describe the genetic variation for that trait in the population. If an allele frequency is 100% then there is no genetic variation for that trait. Normal distribution This type of distribution, in which the frequency is highest near the mean value and decreases toward each extreme end of the range, is called a normal distribution.
The Cerebrum: The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called lobes: the frontal lobe, parietal lobe, occipital lobe, and temporal lobe.
The frontal lobe is divided into two main areas: the motor cortex and the prefrontal cortex. Motor cortex in the frontal lobe. The main function of the motor cortex is to control voluntary movement, including the ones in expressive language, writing, and ocular movement. This cortex is divided into three areas: Primary Motor Cortex
