Detailed explanation-1: -An acquired trait is a characteristic or trait which produces a phenotype which is a result of an environmental influence. Acquired traits are not coded in the DNA of an individual and therefore cannot be passed down to the offspring during reproduction.

Detailed explanation-2: -Acquired traits are traits gained by an individual as a result of his interaction with the environment. These traits do not change the genetic make-up of an organism and hence are not carried down by heredity.

Detailed explanation-3: -Acquired traits include things such as calluses on fingers, larger muscle size from exercise or from avoiding predators. Behaviors that help an organism survive would also be considered acquired characteristics most of the time.

Detailed explanation-4: -An acquired trait is the character developed in an individual as a result of environmental influence. These traits are not coded by the DNA of a living organism and therefore cannot be passed on to future generations.

Detailed explanation-5: -Polygenic inheritance can be explained by additive effects of many loci: if each “capital” allele contributes one increment to the phenotype. With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
