Homologous chromosome. eukaryotic genome. List of sequenced eukaryotic genomes. They are typically 10 -- 300 kb in length , and bear greater than 95 % sequence identity .. Base pair#Length measurements. sequence identity. Sequence alignment#Phylogenetic analysis. Though rare in most mammals , LCRs comprise a large portion of the human genome owing to a significant expansion during primate evolution .. human genome. human genome. primate evolution. Evolution of primates. Misalignment of LCRs during non-allelic homologous recombination -LRB- NAHR -RRB- is an important mechanism underlying the chromosomal microdeletion disorders as well as their reciprocal duplication partners .. homologous. Homologous chromosome. non-allelic homologous recombination. non-allelic homologous recombination. chromosomal microdeletion disorders. Microdeletion syndrome. Many LCRs are concentrated in `` hotspots '' , such as the 17p11-12 region , 27 % of which is composed of LCR sequence .. NAHR and non-homologous end joining -LRB- NHEJ -RRB- within this region are responsible for a wide range of disorders , including Charcot -- Marie -- Tooth syndrome type 1A , hereditary neuropathy with liability to pressure palsies , Smith -- Magenis syndrome , and Potocki -- Lupski syndrome .. homologous.
