Iyini i-locus (ku-genomics)?
Ezakhiweni zofuzo nasezakhi zofuzo, i-locus iyindawo ethile, engaguquki ku-chromosome lapho kutholakala khona i-gene ethile noma umaka wofuzo. I-chromosome ngayinye inezakhi zofuzo eziningi, kanti i-gene ngayinye inendawo noma indawo ehlukile; kubantu, inani eliphelele lezakhi zofuzo ezifaka amaprotheni kusethi ephelele ye-haploid yama-chromosome angu-23 lilinganiselwa ku-19,000<unk>20,000.  Ama-gene angaba nezinhlobonhlobo eziningi ezaziwa ngokuthi ama-allele, futhi i-allele ingase futhi kuthiwe ihlala endaweni ethile. Amangqamuzana e - diploid noma e - polyploid anezinhlayiya zezakhi zofuzo ezifanayo endaweni ethile abizwa ngokuthi ama - homozygous ngokuphathelene naleyo ndawo, kuyilapho lawo anezinhlayiya zezakhi zofuzo ezihlukile endaweni ethile abizwa ngokuthi ama - heterozygous. Uhlu oluhleliwe lwezindawo ezaziwayo ze-genome ethile lubizwa ngokuthi ibalazwe lofuzo. Ukwenza ibalazwe lezakhi zofuzo inqubo yokunquma i-locus noma i-loci ethile ephethe ukukhiqiza i-phenotype ethile noma isici sezinto eziphilayo. Ukwenza ibalazwe lokuhlangana, okwaziwa nangokuthi "ukwenza ibalazwe lokungalingani kokuxhumana", kuyindlela yokwenza ibalazwe lezinhlobo zezimpawu eziningi (i-QTLs) ezisebenzisa ngokunenzuzo ukungalingani kokuxhumana komlando ukuxhumanisa ama-phenotypes (izici ezibonakalayo) nama-genotypes (umthethosisekelo wofuzo wezinto eziphilayo), ukudalula izinhlangano zofuzo.
