To find out how they form
Answer:
A homozygous dominant trait can be described as a trait in which both the alleles of a gene are the dominant one. For example, the AA genotype of the 80 brown gerbils.
A heterozygous trait can be described as the trait in which one of the alleles is dominant and the other is recessive. For example, the Aa genotype of the 64 brown gerbils.
A recessive trait can be described as a trait in which both the alleles are recessive. For example, the aa genotype of the black gerbils.

Answer: True
Explanation:
The cerebrum and the cerebellum are parts of brain:
Cerebellum: lies under the cerebrum. Its purpose is to coordinate movements of the muscles, to maintain posture and balance.
Cerebrum: is the main portion of the brain, which consists of hemispheres right and left. It performs higher functions such as reading vision, touch, hearing, reasoning, emotions, and thinking.
They both contain a gray mater in their surface cortex and deeper nuclie whose function is related to motor control, coordination , precision, and balance.
Hence, the statement is true.
Answer:
Stabilizing selection
Explanation:
Stabilizing selection is the most common form of natural selection that is not easy to notice in a population as the change is less drastic. It occurs when average or intermediate phenotypes of a trait in a population are favored, while the extreme phenotypes of that trait are not favored by the forces of natural selection. Over time, intermediate or non-extreme traits become more common in the population, while extreme traits become less common.
Hey you yes you, I have the answer you need!
The brain sends messages via the spinal cord to peripheral nerves throughout the body that serve to control the muscles and internal organs. The somatic nervous system is made up of neurons connecting the CNS with the parts of the body that interact with the outside world.
Hope this helps!!
