WebIn meiosis, the chromosome or chromosomes duplicate (during interphase) and homologous chromosomes exchange genetic information (chromosomal crossover) during the first division, called meiosis I. The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes. When chromosomes duplicate the copies are? WebA haploid cell is a cell containing exactly one set of each chromosome. (e.g. A, B) A diploid cell is a cell containing two sets of each chromosome.
