Each chromosome has a distinct banding pattern, and each band is numbered to help identify a particular region of a chromosome. This method of mapping a gene to a particular band of the chromosome is called cytogenetic mapping. For example, the hemoglobin beta gene (HBB) is found on chromosome 11p15.4.
Idiograms provide a pictorial reference point that is useful for locating the positions of individual genes on chromosomes, as well as for identifying various abnormalities associated with a...
25 paź 2021 · Chromosomes can be analyzed from living tissue and arranged in a karyotype (figure 13.1). Chromosomes can be sorted into the autosomal pairs (twenty-two) and sex chromosomes and classified to determine any abnormalities. A normal karyotype for a female is 46,XX, and a male is 46,XY.

Physical maps specify the distances between landmarks along a chromosome. Ideally, the distances are measured in nucleotides, so that the map provides a direct description of a chromosomal DNA molecule. The most important landmarks in physical mapping are the cleavage sites of restriction enzymes.
Two copies of chromosome 11, one copy inherited from each parent, form one of the pairs. Chromosome 11 spans about 135 million DNA building blocks (base pairs) and represents between 4 and 4.5 percent of the total DNA in cells. Identifying the genes on each chromosome is an active area of genetic research.
