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 cerebral cortex is responsible for higher brain functions like language and memory. The cerebral cortex is a layer of the brain responsible for complex functions. The cerebral cortex is the outermost layer of brain.View slideshow of images above.he cerebral cortex is responsible for higher brain functions like language and memory.
