All Parrotlet mutations are autosomal-recessive unless otherwise indicated.|
This means that the birds gender has no efect on the mutation, and that a bird needs two copies of a specific gene in order to express it.
"Secondary" Mutations are phenotypes that arise when a bird has more than 1 mutation expressed at a time. Only important combinations listed at this time.
Most genetics technical terms are linked to the appropriate section of the Basic Genetics page. Simply click on these to be taken to an explaination of the term.
