Gene dosage is the number of copies of a particular gene present in a genome. [1] Gene dosage is related to the amount of gene product (proteins or functional RNAs) the cell is able to express. Since a gene acts as a template, the number of templates in the cell contributes to the amount of gene product able to be produced.
These DNA kits for dogs give you way more information than your dog’s breed composition. Many of the kits can be upgraded to include more health and trait testing or allergy and age tests.
In 1974 J. Nerup and others discovered that there is a link between diabetes and MHC genes. Dog leukocyte antigen has been found to be the genetic component associated with canine diabetes. The common alleles/haplotypes found in diabetes prone breeds (Samoyed, Carin Terrier, and Tibetan Terrier) are DLA DBR1*009, DQA1*001, and DQB1*008.
In genetics, the gene density of an organism's genome is the ratio of the number of genes per number of base pairs, usually written in terms of a million base pairs, or megabase (Mb). The human genome has a gene density of 11-15 genes/Mb, while the genome of the C. elegans roundworm is estimated to have 200.
The AMY1 gene is an excellent example of how gene dosage affects the survival of an organism in a given environment. The multiple copies of the AMY1 gene give those who rely more heavily on high starch diets an evolutionary advantage, therefore the high gene copy number persists in the population.
Forever Friends, a spin-out company from Oxford University, hopes to dramatically expand the lifespan of dogs using new gene-editing technology. This startup wants to use gene-editing to extend ...
Although the K a /K s ratio is a good indicator of selective pressure at the sequence level, evolutionary change can often take place in the regulatory region of a gene which affects the level, timing or location of gene expression. K a /K s analysis will not detect such change. It will only calculate selective pressure within protein coding ...
According to a new study, it doesn't really make sense to calculate a dog's age the traditional way — by multiplying its "human year" age by seven. The actual formula, it turns out, might mean ...
