Note that for each recessive condition there is, more or less, a corresponding dominant condition. However, in many cases the dominant condition is simply "normal" or "healthy".

"Wild-type" alleles are more likely to be dominant than recessive. This is because most of the alleles that are carried by an organism produce functional gene products which therefore have an ability to dominate phenotypically alleles that fail to produce functional gene products. This is not to say that recessive alleles are lacking from wild populations but instead that most alleles which fail to contribute positively to phenotype will tend to fail to survive within populations.
