both depending on the type of porphyria
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
Alleles can be dominant or recessive

ALA dehydratase deficiency porphyria is an extremely rare form of porphyria. It is an autosomal recessive disorder with only a few cases reported worldwide. Symptoms can vary widely among affected individuals.
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
Recessive
recessive
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.
is restless leg syndrome dominant or recessive
In a situation where both a dominant and recessive allele are present in a gene pair, the dominant allele will be expressed phenotypically. The presence of a dominant allele overrides the expression of the recessive allele.
it is dominant
