The number of secondary vibrissae in the mouse is normally 19. The tabby gene reduces this to about half and causes a marked variability of vibrissa number. Selection on tabby mice for increase and decrease in vibrissa number has been successful. These selection lines were maintained in segregation for + and Ta alleles, and this selection, practised solely on tabby mice, has resulted in both an increase and decrease in vibrissa number in normal mice.

Seven Generations

A selection experiment for vibrissa number in tabby mice has been extended for 13 generations. Progress of selection for the first seven generations has already been reported. The results of the next six generations of selection are given and the whole experiment is considered with regard to (1) the shapes of the frequency distributions for the three genotypes (+, Ta+, and Ta�) for succeeding generations; (2) limits to phenotypic variation, i.e. canalization mechanisms; and (3) reproductive fitness.

Selection For

Selection for increased and decreased total number of secondary vibrissae has been practised on the mutant mice of a stock in which the tabby gene is segregating. Five separate groups of vibrissae contribute to the total number and differences were found in the response of individual groups of vibrissae to selection. These differences occur both in the main selection experiment and in subsidiary experi-ments based on rare non-tabby mice with abnormal scores which occur with very low frequency in ordinary mouse stocks.

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.
