Gene mutations are sudden changes that occur in genes, that is, it is the process by which a gene undergoes a structural change. Mutations are distinguished from aberrations in that they are changes at the point level, involving the elimination or replacement of one or a few nucleotides in the DNA strand.

The addition or subtraction of bases alters the genetic code, defined by the sequence of three adjacent bases in the mRNA, and consequently it can change the type of amino acid included in the protein chain and, ultimately, it can change the phenotypic expression.

The replacement of a purine (adenine and guanine) with another purine, or a pyrimidine (cytosine and thymine) with another pyrimidine is called a transition. The replacement of a purine with a pyrimidine, or vice versa, is called transversion.

The genetic derivative is one of the basic mechanisms of evolution, associated with natural selection, activated and mutated. This mechanism, especially important in small threats, can be defined as a change in allele frequencies that occurs in a totally random manner. Although it also uses the genetic makeup of a population, it can differentiate natural selection by not producing adaptations

In the case of natural selection, the gene that passes on to the next generation is the one that provided a better adaptation to the environment. In genetic drift, the gene that passed on to the next generation was the one that was most “lucky”.

Answer&Explanation:

Mutation refers to a chance in an organism's DNA, this means a change in hereditary traits of that's organism.

This change in DNA will change how an organism behaves,looks like and it's physiology. This mean an overall life of that organism changes , this makes mutation a huge crucial aspect of evolution, because it is the major aspect that result to genetic variation and changes in organisms.

how population size affects the generation and maintenance of genetic diversity under this model of drift/mutation balance?

Genetic drift reduces genetic variation in a population. This is because genetic drift causes changes in how frequent certain alleles are which occurs just randomly , this is very likely to have a major affect in a small population but not much in a large population.

rodikova [14]

Answer:UCS; UCR---c

Explanation:

UCS (Unconditioned stimulus   is any stimulus that can trigger or cause a response without the subject having any knowledge of that stimulus, which leads to the subject giving an Unconditioned response(UCR) which occurs spontaneously  and due to reflex.

Shining a bright light directly into a person's eye,will cause an UCR because the pupil of the person eye will reflexively constrict. The bright light that triggered  the reflective response is the UCS.
