亲本染色体 meaning in Chinese

parental set of chromosome

There are two main types of nuclear division : mitosis , which results in daughter cells identical to their parents ; and meiosis ( reduction division ) , which produces daughter cells which have half the number of chromosomes of their parent cells , and in which the genetic material has been recombined
核分裂有两种主要的类型：一种为有丝分裂，即子代细胞与亲本相同，另一种为减数分裂，其产生的子细胞所含的染色体数为亲本染色体数的一半，基因在分裂过程中发生了重组。
