haplo-

Single or simple.

Greek haploos, single.

In genetics, a haploid cell is one that has only a single set of unpaired chromosomes, for example a sperm or egg cell in humans. Organisms which are haplodiploid have females which develop from fertilized (diploid) eggs and males from unfertilized (haploid) ones. See also diplo‑.

In writing, haplography is the inadvertent omission of a repeated letter or letters (for example, writing philogy instead of philology, or Missippi for Mississippi); in speech, haplology is a similar omission of a sound or syllable (for example, saying probly when probably is meant).
