Genetic variation allows for mutations to occurs where survival of the fittest occurs. This makes sure that the most adapted creatures survive and are able to pass their genes on to offspring. Thus causing evolution.
Answer:
Fibrous proteins are generally composed of long and narrow strands and have a structural role.
Globular proteins generally have a more compact and rounded shape and have functional roles.
Explanation:
fibrous proteins ARE something, whereas globular proteins DO something.
The genetic change causes alterations in only one or a few nucleotide bases in known as mutation.
A mutation is a change in a brief section of a genome's nucleotide sequence. Another frequently replaces one nucleotide in point mutations; other changes involve the insertion or deletion of one or more nucleotides.
Errors in DNA replication or the harmful effects of mutagens, such as chemicals and radiation, which react with DNA and alter the architecture of individual nucleotides, are the leading causes of mutations.
DNA repair enzymes are present in all cells and work to reduce the frequency of mutations. These enzymes reduce genetic information loss, double-strand break formation, and DNA crosslinking by repairing DNA damage.

Answer:
50/50
Explanation:
Each of us has two ABO blood type alleles, because we each inherit one blood type allele from our biological mother and one from our biological father. A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.
