Goat Eye Color Genetics
Goat eye color is complex due to their being variances in eye color. It should also be noted that some goats have eyes in which only part of the iris is blue (this also occurs in dogs). Such animals are most likely heterozygous blue eyed and are considered genetically blue-eyed, even if only the tiniest portion of the iris is blue, and they can still have offspring with completely blue eyes.
Goat eye color can vary, but can humans get blue eyes from goats? Learn about goat eye color genetics and how it might affect human eye color. Since blue eyes are a dominant trait, if a goat has BROWN EYES, then you can assume that the goat has bb eye color genetics. If a goat has blue eyes, then they can be heterozygous for blue eyes (B b) or homozygous for blue eyes (BB) based upon which genes they received from their parents.

Silver is a unique, dominant modifier which works by changing the hair over the entire goat to a silvery-grey color. This modifies any agouti pattern, although looks most drastic on black or darker colored goats. EYE COLOR blue eyes/ marbled eyes are dominant to normal brown eyes some brown based goats have somewhat lighter eyes than black based goats ANGORA.
The genetics behind what causes a goat to be polled or blue-eyed is one of the most misunderstood phenomena in the goat world. It starts with a simple misunderstanding of what dominant and recessive mean when we're talking about genes. Whether the goat has blue or brown eyes.

Genotype - the specific allelic combination for a certain gene or set of genes. Allele - one alternative form of a given allelic pair; blue and brown are the alleles for the eye color of the goat; more than two alleles can exist for any specific gene, but only two of them will be found within any individual. A homozygous blue-eyed goat (with two copies of the allele) passes the gene to all its offspring and they will all have blue eyes.
Color Genetics The genetic control of color in goats is complicated, but can be broken down into components that are fairly easily understood. Confusion usually comes from not realizing that final color is the result of the interaction of several different components. Each component resides at a separate locus, and at each locus various choices occur.

The sum of the choices made at each locus. However, the expression of blue eyes can vary due to the complex genetic interactions involved in eye color inheritance in goats. Understanding the genetics of eye color in goats involves considering multiple factors, including the possibility of carrying genes for other eye colors and the specific combinations of genes inherited from parents.
