Pairs of chromosomes that are not identical but have genes for the same trait arranged in the same order Homologous Chromosomes Each pair of cells has one chromosome from the mother and one chromosome from the father
1 Genetic = The length of DNA of the gene responsible for a trait has been identified and its sequence determined. 2  Genetic = the gene responsible for a trait has been sequenced, and we know the molecular biology of how the gene product works and how mutations in it produce different results.n allele represents one or more DNA sequences in a gene that produces a particular phenotypic result. Several different mutations might cause a gene to produce a defective protein. All of these mutations might be lumped into a single allele-the gene in a form that produces a defective protein.
