Diploid vs Haploid (Edexcel IGCSE Biology)

Revision Note

Diploid vs Haploid

  • A diploid cell is a cell that contains two complete sets of chromosomes (2n)

    • These chromosomes contain the DNA necessary for protein synthesis and cell function

    • Nearly all cells in the human body are diploid with 23 pairs (46) of chromosomes in their nucleus

  • Haploid cells contain one complete set of chromosomes (n)

    • In other words they have half the number of chromosomes compared to diploid cells

    • Humans have haploid cells that contain 23 chromosomes in their nucleus (no pairs)

    • These haploid cells are called gametes and they are involved in sexual reproduction

    • For humans they are the female egg and the male sperm
