Definition

1. Adjective:
   • Having a single set of chromosomes: Describes a cell or organism whose nucleus contains one complete set of chromosomes, which is the typical state of gametes (e.g., sperm and egg cells) in animals.

Usage

• The term "haploidic" is used primarily in the fields of biology and genetics to describe the chromosomal state of a cell or organism. It is synonymous with the more common term "haploid."
• It is often contrasted with "diploid," which describes cells or organisms with two complete sets of chromosomes.

Examples

• Adjective:
  • The sperm and egg cells are haploidic, each containing half the genetic material of a normal body cell.
  • In this life cycle stage, the organism exists in a haploidic form.

Advanced Usage

• "Haploidic number (n)": Refers to the number of chromosomes in a single set. For humans, the haploidic number is 23.
  • The haploidic number for this species is 12.

Variants and Related Words

• Haploid (adj): The more frequently used synonym for "haploidic."
  • Haploid cells fuse during fertilization to form a diploid zygote.
• Haploidy (n): The condition of being haploid.
  • Haploidy is a crucial phase in the alternation of generations in plants.

Synonyms

• Monoploid: Having a single set of chromosomes. (Note: In strict usage, "monoploid" can sometimes refer to a basic chromosome set, but it is often used interchangeably with "haploid" in many contexts.)
• Haploid: The direct and most common synonym.

Antonyms

• Diploid: Having two complete sets of chromosomes, one from each parent.
• Polyploid: Having more than two complete sets of chromosomes (e.g., triploid, tetraploid).
