Patterns of inheritance |
The manner in which a particular gene trait or disorder is passed through the generations |
genes |
|
|
gene |
the basic physical unit of heredity; a linearsequence of nucleotides along a segment of DNAthat provides the coded instructions for synthesisof RNA, which, when translated into protein,leads to the expression of hereditary character. |
