Ichromosome

IiChromosomes zizakhiwo ezifumaneka embindini (wenucleus) weeseli ezithwala iziqwenga ezinde zeDNA. I-DNA yinto yokugcina izinto zemfuza. Yindawo yokwakha umzimba womntu.

IiChromosomes zikwanazo neeproteni ezinceda i-DNA ikwimo efanelekileyo.

IiChromosomes ziza ngababini. Ngokwesiqhelo, iseli nganye emzimbeni womntu ineesibini ezingama-23 zeekromosomes (ezingama-46 zizonke iichromosomes). Isiqingatha sivela kumama; esinye isiqingatha sivela kutata.

Ii-chromosomes ezimbini (i-X kunye ne-Y chromosome) zichonga isondo sakho njengendoda okanye ibhinqa xa uzalwa. Babizwa ngokuba ngama chromosomes esini:

• Abafazi bane-2 X ii-chromosomes.
• Amadoda ane-1 X kunye ne-1 Y chromosome.

Umama unika umntwana i-X chromosome. Utata anganegalelo ku-X okanye ku-Y. I-chromosome evela kutata yiyo egqiba ukuba umntwana uzalwe eyindoda okanye ibhinqa.

Ii-chromosomes esele zibizwa ngokuba zii-chromosomes ezizenzekelayo. Ziyaziwa njengezibini ze-chromosome 1 ukuya ku-22.
