Résumé

Hotfoot (ho) mutation is a recessive trait in mice, characterized by motor disorder and male sterility, that maps to chromosome 6. We have identified a transgenic mouse pedigree with a similar trait. Using genetic and molecular approaches, we have demonstrated that the foreign DNA element is located in or near the ho locus. This new allele, designated ho^Jwg and presumably created by insertional mutagenesis, should make it possible to clone the ho gene. Male infertility in ho^Jwg male homozygotes was determined to be due to inability of sperm to penetrate the zona pellucida. This was demonstrated by rescuing mutant males by a new technique of gamete micromanipulation, zona pellucida drilling. These findings show that zona drilling is useful both for analysis and preservation of animals with reduced male fertility.
