A Maternal Effect on Vibrissa Score Due to the Tabby Gene

Abstract

An experiment in selection for the number of secondary vibrissae in the house mouse is being conducted on a stock in which the tabby (Ta) gene is segregating. A maternal effect on the vibrissae scores of the progeny of mutant females was observed. This has been investigated in the selection line, stocks derived from it, and Ta/inbred backcross stocks.
