Abstract excerpt
The t complex responder (Tcr) encoded by the mouse t haplotype is able to cause phenotypic differences between t and + sperm derived from t/+ males, leading to non-Mendelian inheritance. This capability of Tcr contradicts the concept of phenotypic equivalence proposed for sperm cells, which develop in a syncytium and actively share gene products. By analyzing a Tcr minigene in hemizygous transgenic mice, we show...
