Back To Basics: Information On Black Labradors
Labradors are one of the most popular and talked about dogs in the United States. Known both for their easy going temperaments and their trainability, these dogs are loveable and outgoing pets. There are several different variations of the labrador, each of which results from either genetics or environmental changes. One of the main variations is in color; this is a genetic variation. The labrador can be one of three colors: chocolate, yellow, or black. Have you ever wondered why there are different colored labs? Have you ever wanted to learn more information on black labradors, or chocolate labradors, or yellow labradors? Read on to learn about the genetic aspects of the color variations, as well as to learn more information on black labradors.
A Brief Lesson In Genetics
Before you learn any information on black labradors, you should learn about how it is determined that labradors will be black in the first place. So how do labradors get to be a certain color? Well, as previously stated, there are three phenotypes (physical colors) that are acceptable for labradors: black, yellow, and chocolate. However, there are nine possible genotypes (genes combinations) that can result in these phenotypes. It is important for breeders, specifically, to know the genotype of their dog; this will tell them what the phenotype of the puppy will be when they breed two dogs together.
Ready to learn more interesting information on black labradors? Black labradors are solid black in color, although some black labradors have a white spot on the chest. Additionally, some black labs have white hairs between the footpads and toes of black labradors. An interesting piece of information on black labradors is that there are more black labradors than either yellow labradors or chocolate labradors, and that black labradors are preferred by breeders. Black labradors have come to be more common than either yellow labradors or chocolate labradors because black is the dominant color gene. Thus, if a black labrador carrying two dominant black genes is crossed with a homogenic yellow dog or a homogenic chocolate dog, then the dominant black gene will overpower the other genes.
To learn information on black labradors, one should first try to understand the genetic information on black labradors. You will appreciate the beauty of this particular phenotype as a result and never look at a black labrador the same way again.
