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.
An overview of the primary motor cortex function tells us that various regions of the cerebral cortex are involved in planning of the voluntary motor functions in the human body.The primary motor cortex function also includes the subsequent processes like controlling and executed the planned motor action.he primary motor cortex function is to generate the neural impulses that are required for the execution of the motor activities in the human body. The other parts are grouped under the category of secondary motor cortex and these include the posterior parietal cortex, premotor cortex and supplementary area cortex.
