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.
â¢ Students can identify the lobes of the cerebral cortex: frontal, parietal, occipital, and temporal. â¢ Students can explain the functions of the major brain parts. â¢ Students can identify the components of a neuron: cell body, dendrites, and axon. â¢ Students can explain the process of neurotransmission.MAJOR PARTS OF THE BRAIN Cerebral CortexThe cerebral cortex is the largest part of the human brain, making up more than 75 percent of this organ.
