A DNA is a genetic material that contains all the genetic information of an organism. A DNA is packaged and condensed into a threadlike material known as chromosome and chromosomes are found in the nucleus of a cell.

Answer:
Option B, a generation
Explanation:
A pedigree is a tree diagram that represents the relationships between different individuals based on certain facts and medical(genetic evolutionary) histories. Basically , the branches of the tree represents the generations which allows the researcher understand how certain genetic characteristics or traits are transmitted with in a family
Such as transmission of any genetic diseases from one generation to the other.
Hence, option B is correct
Variations in evolution usually refers to variation of genes at a particular loci. This differs from diversity which is the total of genetic differences within a population. Speciation is the reproductive isolation of a subset of a population.
Quick reactions/reflexes which do not need to be process by the brain in order to determine a response.
