同义词 amitosis,cellular division,mitosis
cell divisionnoun formation of cells by dividing
amitosis,cellular division,mitosis A genetic map describes the physical location of genes along a chromosome. The closer two genes are together, the less likely they are to separate and cross over in meiosis.

It is due to the lack of homologous pairs of chromosomes, so chromosomes cannot pair in meiosis, and the resulting gametes may have extra or missing chromosomes.
这归因于染色体同系对的缺乏，以至于在减数分裂中染色体不能配对，导致配子有可能有额外或缺失染色体。 plb.snnu.edu.cn
