Coat Color Phenotypes in the F₂ Generation of a Wild Boar/Large White Intercross According to the Genotypes at the Dominant White (I/KIT) and Extension (E/MC1R) Loci

I/KIT		E/MC1R
I/KIT		E ⁺ /E ⁺	E ⁺ /E^p	E^p/E^p
I/I	white	white	white
I/I^p	white	white	white
I/i	W/S (7/15)[i]	W/S (11/20)[i]	W/S (2/12)[i]
I^p/i	patch	patch	—[ii]
i/i	wild type	wild type	black spots[iii]

[i] (W/S) White but the proportion indicated showed pigmented skin spots with white hair or intermingled black and colored hair (roaning).

[ii] This phenotype could not be judged, as no good quality slides were available for the few animals with this genotype.

[iii] These pigs are white with black spots or red with black spots (see Mariani et al. 1996).
