What is Diploid? (Meaning and Definition)
Diploid:
A diploid is a cell or an organism consisting of two sets of chromosomes — one set inherited from each parent. These cells have a pair of each chromosome (2n), making them essential for sexual reproduction.
Key Points:
- Symbol: Diploid cells are represented by 2n, where ‘n’ is the number of chromosomes in a single set.
- Examples: Most animal cells, including human body cells (somatic cells), are diploid with 46 chromosomes (23 pairs).
- Exception: Gametes (sperm and egg cells) are haploid (n) and contain only one set of chromosomes.
Diploid vs. Haploid:
- Diploid (2n): Two sets of chromosomes (body cells).
- Haploid (n): One set of chromosomes (sex cells or gametes).
Importance of Diploid Cells:
- They maintain genetic stability through mitosis.
- Facilitate genetic variation through meiosis and fertilization.
- Help in growth, development, and tissue repair.
