  • Relevant phenotypes are more fully described at appropriate points in the text. The abbreviation (m+z-) refers to animals homozygous for a given mutation but derived from a heterozygous mother carrying a wild-type allele for the relevant gene; (m-z-) refers to homozygous mutants derived from homozygous mutant mothers.
