Genetics, an Introduction

Working out genetics of genes on punnett squares. Examples of how genes work.

Meanings of "Genetic"

genetics = some portion of the trait is inherited in some way.
genetics = the trait is controlled by some combination of named Mendelian genes, which may be may be identified as being located on a particular chromosome, and near some other genes.
Genetics = The length of DNA of the gene responsible for a trait has been identified and its sequence determined.
Genetics = the gene responsible for a trait has been sequenced, and we know the molecular biology of how the gene product works and how mutations in it produce different results.

Genetics, Heredity and Heritability

Heritability is the extent to which the phenotype is determined by the genetic makeup of the individual. Some traits are purely driven by genetics, and these traits have a high heritability. Other traits are strongly influenced by the individual's environment, and their heritability is low.
