Is the hairless gene dominant or recessive?

Is the hairless gene dominant or recessive?

“Except there’s a twist,” says Gina DiNardo, vice president of the American Kennel Club. “Some American hairless terriers do have hair.” Because the hairless gene is recessive, all it takes is one dominant hair gene to make the dogs produce a wiry coat, she says.

Could a yellow dog have a heterozygous genotype?

The yellow parent only carries the recessive allele. This indicates that every puppy must have inherited a dominant allele from the brown parent. The most likely genotype of the brown parent would be homozygous dominant, which would lead to all puppies being heterozygous and brown.

What type of animal is a Mexican hairless?

Sometimes known as the Mexican Hairless dog, the xoloitzcuintli (pronounced “show-low-itz-QUEENT-ly”) gets its name from two words in the language of the Aztecs: Xolotl, the god of lightning and death, and itzcuintli, or dog.

What is the genotype of a heterozygous dog?

Explanation: If the dog with the unknown genotype is heterozygous, our cross would be: Aa x aa. In this model, A represents the dominant yellow-fur allele and a represents the recessive black-fur allele. We the black furred dog has to be genotype aa because he displays the recessive phenotype.

Why are Mexican dogs hairless?

The xolo’s hairlessness (save for a tuft or two of hair on top of the head or on the tail) is the result of a genetic mutation that is also responsible for the dog’s lack of premolars. This distinctive dental trait makes identifying the remains of xolos in archaeological contexts relatively easy.
