Variations, traits
Not all members of a species are the same. Every species exhibit variations. Traits, like eye color, are passed from parent to offspring.
Genetic variation is the subtle differences in the DNA sequence in each individual’s genomes. Genetic variation results in various forms or alleles of genes that determines distinct traits such as eye color, skin color, shape of face, and hair color that can be passed on from parents to offspring.
While I'd skip the whole idea of reading specific bytes, if it's really worth while for your program you'll probably need to take charge of the file reading yourself so that you can keep track of exactly where you are in the file at all times.
When the blood plasma becomes less concentrated and the level of ADH decreases, aquaporins are removed from collecting tubule cell membranes, and the passage of water out of urine and into the blood decreases.
No..a mutation in human skin acquired is called a somatic mutation, and it cannot be passed on. Mutations can only be passed on from sex cells (aka germ-line mutations can be passed onto offspring)
