Theory of evolution includes the idea that the species are related to each other and changes with time. It states that inherited variation allows some members of a population to be more fit than others.
What is theory of evolution?Theory of evolution is based on genetic variation which affect phenotype of an organism in particular population.
The main theories of evolution is as follows:
Lamarkism: It is theory of inheritance of many acquired characters.Darwinism: it postulates the theory of natural selection.Mutation theory of evolution: proposed by Hugo de Varies.Neo-Darwinism: it is modified version of natural selection theory.According to these theories, traits are inheritable, species changes over time, inherited variation allows some members of a population to be more fit than others.
Thus, the correct options are A, B and E.

Could a man with Type O be the father of a Type AB child? Explain.
Answer:
No, because someone with blood type O has the genotype OO because O is recessive. One parents would need one allele to be A and the other parent would need one allele to be B for the child to be AB. But the man does not have an A or B allele, so it is not possible for him to be the father of a child with blood type AB.
