Polygenic inheritance is when a group of gene pairs act together to produce a trait.
genes are actually segments or short lengths of dna,in this way it is related to dna. we can define gene as the basic units of inheritance which determine the inherited charaters,they contain coded biological information in the form of base sequence.

Linked gene inheritance. In humans, it is called x-linked inheritance; sex-linked inheritance is when the trait is carried on the X chromosome.

Dominant Inheritance is when one parent has a dominant gene and the other has a recessive gene. The dominant gene overpowers the recessive gene, and only the dominant gene is phenotypically expressed.Source: http://www.accessexcellence.org/RC/VL/GG/recessive.phpSome examples are variegate porphyria, Huntington's disease and myotonic dystrophy.source: http://genome.wellcome.ac.uk/doc_WTD020849.html
