Dominance of TraitsChelsea Denhard

Basic Terms

Trait: a specific characteristic (color, hair, etc.)

Hybrid: offspring of crosses between parents with different traits

Incomplete Dominance: when an allele isn’t completely dominant over another

Codominance: when both alleles are seen

Incomplete Dominance

Even with purebred dogs, incomplete dominance is shown, as seen in the next slide, when one trait, in this case color, isn’t completely dominant.

You can see incompletedominance here. Kinzel and

Ivan’s puppies aren’t onespecific color. The traits

aren’t completely dominant.

Hybrids If a dog isn’t a purebred it’s a hybrid. A

Shih-tzu bred with a Yorkie will produce Shorkies, a hybrid. Also, a Poodle and a Yorkie will give you a Yorkie Poo.

Codominance

Looking at hybrids, we can see codominance. Both parents’ genes can be seen.
