ABSTRACT:
The present invention provides a mutant non-human vertebrate, in which all or some of the germ and somatic cells contain a mutation in at least one steroid hormone receptor allele, which mutation is introduced into the vertebrate, or an ancestor of the vertebrate, at an embryonic stage, and which mutation produces a phenotype in the vertebrate characterized by a deficit of functional steroid hormone receptors encoded by the allele. Also disclosed are related methods and constructs.
