Liphatsa tsa lefutso

Liphatsa tsa lefutso ke karolo e khuts'oane ea DNA. Liphatsa tsa lefutso li bolella 'mele mokhoa oa ho aha liprotheine tse ikhethang. Ho na le liphatsa tsa lefutso tse ka bang 20 000 ka seleng ka 'ngoe ea' mele oa motho. Hammoho, li etsa moralo oa 'mele oa motho le hore na o sebetsa joang.

Sebopeho sa motho sa lefutso se bitsoa genotype.

Liphatsa tsa lefutso li entsoe ka DNA. Matla a DNA ke karolo ea li-chromosome tsa hao. Li-chromosome li na le lipara tse tšoanang tsa kopi e le 1 ea lefutso. Liphatsa tsa lefutso li hlaha boemong bo tšoanang chromosome ka 'ngoe.

Litšobotsi tsa lefutso, joalo ka 'mala oa mahlo, li hlahelletse kapa li fetelletseng:

• Litšobotsi tse hlahelletseng li laoloa ke lefutso le le leng ka har'a li-chromosome.
• Litšobotsi tse fetelletseng li hloka liphatsa tsa lefutso ka har'a liphatsa tsa lefutso ho sebetsa 'moho.

Litšobotsi tse ngata tsa botho, joalo ka bophahamo, li khethoa ke liphatsa tsa lefutso tse fetang 1. Leha ho le joalo, mafu a mang, a kang sickle cell anemia, a ka bakoa ke phetoho ea lefutso le le leng.
