«In mammals, in the absence of haploid cells, other approaches have been used to identify key genes, such as interfering RNA, but they are sub-optimal methods. (sciencedaily.com)
Their findings suggest that the loss of haploid cells is due to their limited viability and, therefore, they are replaced by existing diploid cells in the cultures. (sciencedaily.com)
During meiosis, the genome of a diploid germ cell, which is composed of long segments of DNA packaged into chromosomes, undergoes DNA replication followed by two rounds of division, resulting in haploid cells called gametes. (sciencedaily.com)
