Amarine biologist explains that the color of the scales of salmon is a heritable trait. what is a "heritable" trait? the trait can be acquired by experience over a lifetime. the trait can be enhanced by the environmental variables. the trait can be passed down from parent to offspring. the trait can be taught by the parent to the offspring.

The answer is; The trait can be passed down from parent to offspring.

These traits are passed down from parents to offspring through genetic material. Each parent contributes half the genes of the offspring. This occurs through gametes which have half the chromosome number of the parents (hence haploid). The genes in the chromosomes are passed down by Mendelian principles and are responsible for the traits of the offspring.  

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
