Horse Genetics 101--Lesson 1
I am studying genetics, so I can be more knowledgeable about horse breeding. Here are some basic vocabulary words that I learned.
Homozygous -- When a horse carries 2 of the same gene. He or she always passes this gene to all of its offspring.
Breed True -- This refers to color. Horses are said to breed true when breeding two of the same color will always result in a foal of that color.
Dilute/Dilution Genes -- Genes that dilute the horses base color to a lighter color. This includes the cream, silver dapple, champagne and dun genes.
Heterozygous -- When a horse carries only 1 of a gene. Therefore, it only has a 50/50 chance of passing that gene to his/her offspring.
Dominant -- A gene that is expressed IF it is present in the horses genotype
Recessive -- A gene that is only expressed IF the horse has both genes the same at a given gene pair.
Phenotype -- How a horse looks visually.
Genotype -- What genes a horse actually has.
Homozygous -- When a horse carries 2 of the same gene. He or she always passes this gene to all of its offspring.
Breed True -- This refers to color. Horses are said to breed true when breeding two of the same color will always result in a foal of that color.
Dilute/Dilution Genes -- Genes that dilute the horses base color to a lighter color. This includes the cream, silver dapple, champagne and dun genes.
Heterozygous -- When a horse carries only 1 of a gene. Therefore, it only has a 50/50 chance of passing that gene to his/her offspring.
Dominant -- A gene that is expressed IF it is present in the horses genotype
Recessive -- A gene that is only expressed IF the horse has both genes the same at a given gene pair.
Phenotype -- How a horse looks visually.
Genotype -- What genes a horse actually has.

wow nice article. its my first time to know somebody passionate about horses. God bless and take care.
Thanks for stopping by! And yes, I am passionate about horses.
Cheers,
Elizabeth
we're doing genetics in science class! i like the definitions, especially of heterozygous
I guess there is a word for everything, and horse related words seem to be no exception. It's interesting to read the various words and definitions.
This is a great blog!
We have a mare that is Homozygous and she always throws and black foal.

Thanks for the compliment about my blog, Jess! Hope you come back and post often! I will check out yours, too.
Cheers,
Elizabeth
