What is Circulatory system?</h3>
The heart, blood vessels, and blood itself circulate throughout the entire body of a human or other vertebrate through the blood circulatory system.
The blood contains of the red and white blood cells along with plasma and other substitutes of blood.
Also the blood has the function to supply the nutrients to the cells of the body along with transporting carbon dioxide to the alveoli of the lungs.
The circulatory system is a closed pack system with the involvement of various organs like the heart the lungs and plays a crucial role in maintaining the homeostasis of the body.

One hypothesis that explains the result is : A) Two genes are involved with 12:3:1 epistasis, such that A_B_ and A_bb are black, aaB_ is brown,and aabb is green.
Explanation:
- This is a case of Dominant Epistasis.
- When two genes are involved and presence of dominant allele of one gene masks the effect of either allele of the second gene then the epistasis is termed as dominant epistasis.
- In the given case black :brown: green ratio is approximately equal to 12:3:1.
- Here presence of a dominant A allele that is responsible for the black colour masks the effect of either allele of B. Therefore A_B_ and A_bb produces black beetles
- Again , absence of dominant A allows B to express itself and Brown beetles are produced thus aaB_ is brown.
- When both the genes are present as recessive alleles, neither brown nor black colour is expressed and the beetles are green.Thus, aabb are green.

What is Poliomyelitis?</h3>
It is a disease that threatens life, and a disabling caused by the poliovirus.
Poliomyelitis is a very contagious disease that can be transferred from one individual to another individual.
Therefore, polio is asymptomatic or mild with headache, sore throat, fever, and nausea if virus enters the central nervous system motor, neurons can be infected and destroyed.
