K Locus In Coat Color

1053 Words5 Pages

breeds where the A locus does not come into play, any animal that has at least one B allele (and is not "ee"), will be black in pigmented coat. Those dogs, which have two copies of any of several b alleles will be brown. There are at least three such b alleles. Regardless of other loci, any animal with at least one B allele will have a black nose and pads, while those with any two b alleles will have a liver nose and pads. The K locus plays a pivotal role in coat color. This locus is a relative newcomer in our understanding of canine color, and includes traits formerly attributed by some to other genes. The dominant allele in the series is KB, which is responsible for self-coloring, or solid colored fur in pigmented areas. This trait was formerly …show more content…

This is called incomplete dominance (or codominance in some cases) and only happens on particular loci. The resulting dog will have a mixture of alleles, but its markings will generally lean more towards the more dominant allele. For example, the S series controls white markings and the alleles in it display incomplete dominance over the other. Sp is the allele for piebald (white markings covering 50% or more of the body), and S is the allele for no white markings. A spsp dog will be piebald, but even though S is slightly more dominant than sp, an Ssp dog won’t necessarily just be solid-colored. Instead it may have some minimal white markings, because it is able to partly express its more recessive allele (piebald). Incomplete dominance and codominance are more or less the norm for most genes, however many of the dog color genes do happen to have a simple dominant/recessive relationship (Schmutz, Berryere, Goldfinch, …show more content…

Setting The study will be conducted at the Barangay New Visayas, Panabo City, Davao del Norte. Participants We will be interacting with the owners of the dogs for the gathering of data via questionnaire. Approximately, 100 residences will be surveyed for the study. Measures The measure to be used in the study will be the survey responses of the residents. Procedure I. Permit Acquisition Before conducting the survey, we will obtain permits from the Barangay Hall of New Visayas, Panabo City which will allow us to gather and collect the necessary data for the study. II. Collection of Data For this study, we will do a survey in order to determine the fur color variation of the dogs at Barangay New Visayas, Panabo City, Davao del Norte. We will roam around the vicinity of Barangay New Visayas, Panabo City and look for houses with dog/s and ask for the owners to answer and fill in the prepared questionnaire individually, and as honestly as possible. If given the permission, we will take photos of the dog/s for the researchers’ documentation. We will inform them that their answers would be treated
