WebIn cats, one of several genes controlling fur color is located on the X chromosome. The gene has two versions, or alleles. One form of the gene codes for orange fur (X B), and the other form codes for black fur (X b). While it's difficult to say which allele is dominant and which is recessive, since only one is ever expressed (see below), let's ... WebDNA is a helix-shaped molecule made up of nucleotide base pairs. In each chromosome, sequences of DNA make up genes that control or partially control a number of visible characteristics, known as traits, such as eye color, hair color, and so on. A single gene may have multiple possible variations, or alleles.
