我想知腦有邊12對染色體???
最佳解答:
唔明你問緊乜？你係講緊人類？ 人類除咗生殖細胞（精子同卵子）之外，每個細胞都有２３對（即係４６條）染色體（包括腦細胞），生殖細胞因為要結合成為有２３對染色體嘅受精卵，所以各自只有２３條染色體． 其他生物會唔會係得１２對染色體，就要查下先知啦． 以下係一D關於染色體嘅資料，你自己慢慢睇啦． The human chromosomes Human cells have 23 pairs of large linear nuclear chromosomes, giving a total of 46 per cell. In addition to these, human cells have many hundreds of copies of the mitochondrial genome. All of the human chromosomes have been sequenced and a great deal is known about each of them.
