| abstractText | Results from earlier selection studies indicated that while the size of head spots in mice descended from the Goodale head-spot strain was a quantitative, polygenic trait, head-spot occurrence was probably a qualitative trait inherited by one or two genes. The present study was undertaken to examine this possibility by crossing a head-spot stock with three inbred strains and with two noninbred stocks carrying mutant genes. Observed segregation ratios in the F2 and backcross generations of these crosses were compared to results expected under various models of qualitative inheritance. Evidence of linkage between known loci and a putative head-spot gene also was sought. Results indicated that head spotting was inherited primarily by the action of a recessive autosomal gene, head spot (hs). The action of this gene was subject to modification, in some crosses, by other genes or by environmental factors. Attempts to demonstrate linkage between the head spots and known single-locus traits were unsuccessful. |
