Flashcards

What is meiosis?

A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell.

What is spermatogenesis?

The process by which sperm cells are produced, within the seminiferous tubules.

What triggers ovulation?

The primary trigger is a surge of luteinising hormone (LH), causing the Graafian follicle to rupture and release the ovum.

What process creates four non-identical cells?

The process of cell division that produces four genetically distinct cells, each with half the number of chromosomes as the parent cell.

Study Notes

Genetic Variation and Reproductive Processes

  • Genetic variation increases during meiosis, a process that involves the division of sex cells (gametes) to produce offspring with unique combinations of traits.
  • Spermatogenesis, the process of producing sperm cells, occurs in the epididymis and testes in the male reproductive system.
  • Luteinizing hormone (LH) surge triggers ovulation in the female reproductive system, releasing a mature egg from the ovary.
  • Meiosis is the process where four non-identical cells are created, resulting in genetically unique gametes.
  • The corpus luteum in the female reproductive system produces progesterone, which prepares the uterus for a fertilized egg and maintains pregnancy.
  • The bulbourethral glands in the male reproductive system produce pre-ejaculate fluid, which helps to neutralize acidity in the urethra and lubricate the penis during sexual arousal.
