| | Haploid Embryogenesis (Site not responding. Last check: ) |
 | | The cells of gamete-producing tissue of conifers is haploid, having half the chromosome complement of the sporophyte. |
 | | In conifers, it is only possible to induce haploid embryos from female tissue, in particular, the prothallial cells of the megagametophyte. |
 | | The plants that arise from such cultures are initially stably haploid, but soon develop mixoploid regions, in which tracts of cells with double the chromosome number are found. |
