. A cytological study of haploid Crepis capillaris plants. Karyokinesis; Crepis. Fig. 11. Haploid Crepis capUlaris. Kepresentative microspore groups. number and constitution. The diad which presumably results from division of all the chromosomes, and the tetrad which presumably arises from a diploid PMC, are probably the only ones which produce normal haploid gametes. As noted above, normal pollen grains were very rare. The monad presumably contains the diploid chromosome complex and would be expected to give rise to a diploid pollen Please note that these images are extracted from sca
