The right ventricle is deoxygenated. It is responsible for the pumping of the deoxygenated from the heart to the lungs.
Pleiotropy refers to the phenomenon of a single gene affecting multiple traits. Phenylketonuria is an example of Pleiotropy.
<h3>What is Pleiotropy?</h3>
The production of diverse effects, especially the production by a single gene of several distinct and seemingly unrelated phenotypic effects known as pleiotropy.
Phenylketonuria, generally known as PKU, is a rare hereditary condition that results in an accumulation of the amino acid phenylalanine in the body. The phenylalanine hydroxylase (PAH) gene is altered in PKU. The enzyme required to degrade phenylalanine is produced in part because of this gene. PKU can be seen to behave as a 'complex' trait.
Only 11.1 percent of MHP patients were homozygous, compared to 58.4 percent of individuals with classic PKU. Individuals with mild PKU had a compound heterozygous rate of 72.5% compared to only 35.1% in patients with classic PKU.

Answer:
1.Carbon is small and has four valence electrons; these factors combine into a unique structure that allows it to easily make a chain of carbon atoms. It creates covalent bonds — the strongest bonds between atoms. A covalent bond is one where atoms share electrons to form a bond.
2.But what makes carbon unique is that it can bond with other carbon atoms to create long carbon chains and rings. No other element is capable of forming molecules as large and complex as carbon based molecules (think about it—without carbon chains and rings, there could be no DNA!)
3.Because the carbon-carbon bond is stronger than the silicon-silicon bond, carbon compounds stay together in water while silicon compounds break apart. Besides this, another probable reason for the dominance of carbon-based molecules on Earth is the abundance of oxygen.
