Basic Marking Genetics

 

Solid	H/H		Hooded	h/h hm(l)/hm(l)
Berkshire	H/h		Bareback	h/h hm(s)/hm(s)
Classic Berkshire	H/h  or  h(i)/h(i)		Capped	h(n)/h(n)
American Irish	H/h(?) or h(i)/h(i)		Husky Banded	H/h(i) S/s
English Irish	H/h(i)		Cap Stripe	H/h(n) S/s
Variegated	H(re)h(i) or H(e)h(i)		Essex	H(ro)/H
Dalmatian	H(ro)h(i) H(e)h(i).		Baldie	H(ro)/h
Black Eye White (BEW)	H(e)H(e)

 

Hooded Locus:                                   Incomplete dominate, recessives

Wild type                                            H – fairly dominate

Hooded                                               h – incompletely recessive

Extreme Hooded Pattern:                H(e) – can make BEW, Berkshire, variegated, patched

Restrictive Hooded Pattern:            H(re)

Roberts / Essex:                                H(ro) – in addition to markings, causes fading of coat

Notched                                              h(n)

Irish                                                    h(i)

Down Under                                       h(du)

Hood modifier                                    h(l), lengthens spine stripe

                                                            h(s), shortens stripe

Odd-eyes:  Not controlled by a single gene but in association with white spotting such as American Husky S/s and H(e)
