Summary
Let us go over some key points to what you have learned in the lessons.
- All of the color alleles belong to their own designated loci.
- All of the non-traditional colors of Boston Terriers are recessive genes.
- Genotypes are responsible for genetic traits situated on a chromosome where as pheonotype is a
physical trait.
- Recessive alleles are identified with lower case letters (d) and dominant alleles are identified with upper
case letters (D).
- Brindle is the most common pattern a Boston Terrier can be found in.
- Seal is defined by the AKC as "appearing black except it has a red cast when viewed in the sun or bright
light".
- Red and Brown are genetically the same.
- Hazel is the predominant iris color in red/brown Boston Terriers.
- There are 3 identified mutations of recessive b.
- One of the alleles present and responsible for fawn coloration is ay.
- Banded is the term used to describe the intermingling hairs of a fawn Boston Terrier that are fawn colored
at the base and tipped in black.
- Melanistic masking can be any of the 3 colors: black, brown, grey.
- Cream and white Boston Terriers are most typically born solid white.
- Dried Sea Kelp is a supplement that can be used for darkening pigmentation.
- Honey colored Boston Terriers are most confused with Fawn Boston Terriers.
- Dilute is the only gene that does not have to be carried recessively by sire and dam to produce in a litter,   
it can mutate.
- Steel is the term used to describe dark blue Boston Terriers.
- Blue Bostons that seem to stay the lightest in coat color are those that are heavily brindled.
- A dilute red Boston Terrier whose color is pale with little to no blue hue to the coat is termed a
Champagne.
- The color Boston Terrier whose eyes drastically change from baby blue to light hazel into adulthood is the
lilac/champagne.
- Lilac/champagne and red/brown are the only other documented colors that have been produced by a
phenotypically red/brown sire to red/brown dam mating from pure lineage and proven parentage.
- The only locus in the Boston Terrier breed that is hypothetical is the C locus as it has not been mapped
genetically to date thus remaining a theorized loci.
.
- Albino Boston Terriers are known as Cornaz Albinos and are double diluted.
- Cornaz Albinos can have either blue or green iris color.
- The correct term for what is known as pied in other breeds, but in Boston Terriers is splash.
- MITF is the critical gene in the pigmentation pathway.
- Thanks to Dr. Karlsson's research there is now a test for white factoring/spotting in canines.
- The pattern that is the hardest to come by in Boston Terriers is tricolor.
- To be classified as a tricolor Boston Terrier there must be points at the following locations: eye brows,
cheeks, and between the white socks and color on the legs.
- A predominance of white of the body or head and blue eye(s) are NOT a reason to conclude deafness in
Boston Terriers without a BAER test.
