Chromosome theory of inheritance. generalization that genes are located on chromosomes and that the behavior of chromosomes during meiosis and fertilization accounts for inheritance patterns, also states that mendelian genes have specific loci, chromosomes undergo segregation and independent assortment.
The CFTR gene is located on the long arm of chromosome 7 at position 7q31.2. Geneticists use maps to describe the location of a particular gene on a chromosome. One type of map uses the cytogenetic location to describe a geneâs position.The cytogenetic location is based on a distinctive pattern of bands created when chromosomes are stained with certain chemicals.Another type of map uses the molecular location, a precise description of a geneâs position on a chromosome.ne type of map uses the cytogenetic location to describe a geneâs position. The cytogenetic location is based on a distinctive pattern of bands created when chromosomes are stained with certain chemicals.
