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.
  In short, the cerebral cortex is the outer and largest part of the brain, that covers its smaller parts and is usually easily visible on brain illustrations. It contai â¦ ns gray matter (neurons) responsible for the higher functions of thinking and information processing.he cerebral cortex is the outer layer of the cerebellum. It processes information from the sense organs and controls body movement. The cerebral cortex is not the outer la â¦ yer of the cerebellum.
