n根本就唔係咁既definition
c / x 先係代表number of sets
正如以下個例子
Variation in euploidy for organisms with x=11
Ploidy Nr of chromosomes Somatic Gametic
Diploid 2x=22 2n=22 n=11
Tetraploid 4x=44 2n=44 n=22
Hexaploid 6x=66 2n=66 n=33
Octoploid 8x=88 2n=88 n=44
不過係因為好多人都用錯先會已經冇乜人執著
就好似gene既definition到宜家大學教科書都仲係寫a segment of DNA code for a polypeptide chain / protein
完全忽略左miRNA, lncDNA, siRNA等等既definition
