| May 8, 2013 at 17:29 | comment | added | AndroidPenguin | This is the answer. They all happen with similar frequency, however most are lethal. The less lethal the more common, hence trisomy 21 or Downs being fairly common; however most trisomy 21 foetuses do die before getting to the second trimester. | |
| May 8, 2013 at 17:11 | comment | added | shigeta | this is still quite a likely explanation - there is very little or no data for pregnancies that terminate before the foetus is smaller than a pea. Almost all extra chromosomes for instance come from sperms and ova formation and they may simply not compete for fertilization. | |

add frequency data.
