Abstract

The aim of this project is to locate the position of a major gene controlling broodiness in the genome of the domestic chicken. The experimental approach is based on the observation that White Leghorn chickens (WL) do not become broody whereas bantams (B) are well known for this trait. A major trait gene for broodiness is known to occur on the Z chromosome. A reciprocal cross will be made between WL and B and their offspring will be tested for broodiness. No broodiness should occur for the male WL x female B cross but it should occur for the female WL x male B cross. If this prediction is correct a male from the male WL x female B parents will be mated to female WL. Broodiness in the resulting female offspring should be at a ratio of 1:1. Microsatellite markers currently being developed in the chicken genome mapping programme will then be used to compare Z chromosomes from birds carrying or not carrying the broody gene in order to locate the gene.
