I guess the best way to answer that is genetic variation.... otherwise we would all have the same physical characteristics. This ensures health of a species as some people may be more resistant to a virus than another and so theoretically the fitter and stronger will produce more young and pass on those 'good' genes to more offspring.
Added:
Mutation can produce different molecular forms of the same gene. This is the ultimate reason for alleles. Just remember that mutations are rare..especially beneficial ones or neutral ones that have no effect on the individual.
Alleles are different forms of genes that arise from mutations in the DNA sequence, resulting in variations in the genetic information carried by a specific gene. These variations may lead to differences in the traits or characteristics encoded by that gene. Ultimately, alleles contribute to genetic diversity within a population and are essential for evolutionary processes.
The study of reason is called logic. It involves analyzing and evaluating arguments to determine their validity and soundness. Logic is an important aspect of philosophy and critical thinking.
for this reason ceall are called structural and functional units of life
Yes, two different commissioners of oath can sign two different documents for the same reason. Each commissioner is authorized to administer oaths and affirmations independently, so multiple commissioners can sign separate documents for similar purposes.
The ancient Greek mathematician Eratosthenes is called the "father of geography" for that reason.

All the features of Home Premium are included in Ultimate. There is no reason to go backwards.
For the same reason any other differences exist between individuals - the alleles necessary for the various blood types were present in Adam and Eve and were expressed in various combinations in their descendants.
I see no reason why you would not be able too.
It is the ultimate act of evil to target innocent people for the reason that they are innocent.

Many harmful alleles are recessive because they usually interfere with normal biological processes or functions. To exhibit their harmful effects, both copies of the recessive allele need to be present in an individual, leading to a higher threshold for expression. In contrast, dominant alleles only need one copy to be expressed, making harmful effects more immediate and noticeable.
The ultimate answer is that, in our Universe, it just is. There's no reason it HAS to be that way, but it just is -- whether we like it or not.
No, it is named for a very different reason I'm not sure though what it is
There reason that there aren't any civilians in Hulk Ultimate Destruction is because the civilians run away from a gigantic green monster that looks like it can tear them apart.
There are many different cultures that make up the United States. For this reason the United States is often called a melting pot.
No reason at all.
