61% of emerging diseases is caused by zoonotic pathogens
Explanation:
Out of total emerging diseases zoonotic contributes 61%, that are originated from wildlife. The rate is increasing due to growth of human population, its mobility, frivolous, cultural and their socioeconomic purposes. Air is the major source for spread of infectious diseases. Zoonoses are generally caused by bacteria, viruses and pathogens that are blowout between animals and human beings. Modern zoonoses are Ebola virus and salmonella. One of such direct zoonoses is rabies, that is transformed directly from animal to human.
Dominant' traits will actually disappear faster if they are disadvantageous.
Think about it: if everyone who has even a single copy of a particular allele is at a disadvantage (manifests the phenotype, in this case six fingers), then even single copies are selected against.
In the case of recessive traits, selection occurs only against homozygous carriers, who may be very rare if the allele itself is rare.
A concrete example would be something like Tay-Sachs disease. If the allele that causes this were dominant, every carrier would die before adulthood, and it would occur only as a very rare de novo mutation. But because it is recessive, it persists for now; heterozygous carriers have no disadvantage.
No because we keep putting it into the earth also decomposing animals give off carbon.
