與此相對應,對正交子代染色體的統計結果表明,約l / 3的染色體分裂相擁有35條染色體,而1 / 3的染色體分裂相擁有38條染色體;正交子代的染色體核型也具有多態性,不能統一。The origin of such large amounts of constitutive heterochromatin and their role in karyotype evolution and speciation remain a mystery.
如此大量的結構異染色質的來源及其在染色體組型進化和物種形成中的任務仍是一個謎。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
核分裂有兩種主要的類型:一種為有絲分裂,即子代細胞與親本相同,另一種為減數分裂,其產生的子細胞所含的染色體數為親本染色體數的一半,基因在分裂過程中發生了重組。The tailed primer design protocol is feasible for y - str loci and can be used to develop more multiplex pcr assays of y - str loci. the results of validation prove that the y - a489 - plex multiplex pcr system can be accepted for the forensic dna typing
