INSIGHT

Fertility Fundamentals

  • Fertility is about producing offspring with half the genes from each parent.
  • Germline cells (egg/sperm) are protected, their genes unmodifiable by individual behavior.

Somatic vs. Germline Cells

  • Two cell types exist: somatic cells (most body cells) and germline cells (egg/sperm).
  • Females generate a 'vault' of immature eggs at embryogenesis, containing paired chromosomes.

Chromosome Pairing

  • Fertilization unites 23 single chromosomes from each parent, creating pairs within a single cell.
  • This cell divides, forming the embryo with half of its genes from each parent.
