Majini

Jini chidimbu chidiki cheDNA. Majini anotaurira muviri maitiro ekuvaka chaiwo mapuroteni. Kune dzinosvika zviuru makumi maviri zvemajini mumasero ega ega emuviri wemunhu. Pamwe chete, vanogadzira chirongwa chemuviri wemunhu uye kuti unoshanda sei.

Maumbirwo emunhu anonzi genotype.

Majini anogadzirwa neDNA. Tambo dzeDNA dzinoumba chikamu chemakromosomes ako. Chromosomes ane maviri akaenzana e1 kopi yeiyo chaiyo geni. Iyo geni inoitika munzvimbo imwechete pane imwe chromosome.

Hunhu hwegeneti, senge ruvara rweziso, hwakanyanya kana kudzora.

• Hunhu hukuru hunodzorwa ne1 geni mune maviri echromosomes.
• Hunhu hwekudzokorodza hunoda mageneti ese ari mune maviri majini kuti ashande pamwe chete.

Hunhu hwakawanda hweunhu, hwakadai sehurefu, hunotsanangurwa neinopfuura 1 gene Nekudaro, zvimwe zvirwere, senge sickle cell anemia, zvinogona kukonzerwa neshanduko mune rimwe geni.
