Answer:
Yes, it does have to have a nervous system.
Explanation:
The correct answer is option B, that is, a person with type O blood has two recessive genes.
An illustration of a trait determined by a single gene is blood type. Each human exhibits two copies of the gene for blood type on chromosome pair number 9. One of the copy is inherited from the father and the other one is inherited from the mother. An individual's blood type is determined by which allele he or she inherits from the parents.
In case of blood type O, O is a recessive allele. If an A or B is inherited along with the O gene, the A or B gene decides the blood type of an individual. An individual is considered to have type O only if that person inherits two O genes, that is, a person with type O blood exhibits two recessive genes.

Activities such as walking, talking, blinking, and breathing are controlled by the central nervous system, but laughing is controlled by the brain's right frontal lobe. Hope this helped, have a good day UwU <3
In the gene pool of population with 350 individuals a fixed allele has a frequency of 1(one). Fixed alleles is the alleles that is the only variant that exist for that gene in all population.The frequency of gene pool with a population of 350 is = 1 since the frequency of total alleles =1
