MONOPLOIDY / HAPLOIDY

• Individual having one chromosome set (n) of genome per nucleus is called monoploidy.
• In most cases the gametes will be monoploid with n number of chromosomes.
• During fertilization the parental chromosomes unite together by the fusion of gametes forming diploid number (2n) of chromosomes.
• In diploid taxa, an individual organism with only one chromosome set(n) is called a monoploid whereas species in which all individual with normally only one chromosome set are haploid (also n).
• Male bees, wasps, and ants are monoploid.
