Answer: Holism
Explanation:
Holism is a theory which suggests that parts of the organism are connected, these cannot function independently but as a part of whole organism.
This can be understood as organism as whole is greater than the sum of its parts.
Thus everything about an organism can be understood through the components that is if a person is suffering from brain disease then this may affect the control and coordination of the body this is likely to affect the whole organism.
Lethal alleles cause the death of an organism prenatal or after the birth. Lethal alleles are usually a consequence of a mutation and they can be recessive, dominant or conditional. Since the lethal dominant alleles are harmful whether they are carried in homozygous (e.g.AA) or heterozygous (e.g.Aa) form, a strong selection against them is present and thus these alleles are much more rare.
