Explanation:
Hypothalamus. The hypothalamus is located at the base of the brain. It makes hormones that control hormones released in the pituitary gland. The hypothalamus controls water balance, sleep, temperature, appetite, mood and reproductive behaviors, and blood pressure.
Cerebellum controls balance for walking and standing, and other complex motor functions while the temporal lobe plays the role in processing affect/emotions, language and certain aspects of visual perception.
Crossing over happens in prophase I when the homologous chromosomes are sy naps ed. The two inner chromoatids exchanges sections with each other. This means that after the exchange the inner two chromatids have new combinations of alleles than their parents had. The two outer chromatids still have the parental combinations.So there are more kinds of chromatids ready to go into the gametes than there were before. This is an increase in variation.
