Sexual Reproduction: Meaning & Definition
Sexual reproduction is a biological process in which two opposite-sex parents (male and female) contribute genetic material to produce offspring. This process involves the fusion of male and female gametes (sperm and egg), resulting in genetic variation in the offspring.
Definition of Sexual Reproduction
“Sexual reproduction is the process by which new organisms are created through the combination of genetic material from two different parents of opposite sexes, involving the fusion of male and female gametes.”
Key Features of Sexual Reproduction
Involves Two Parents – Male and female organisms contribute genetic material.
Gamete Formation – Special reproductive cells (sperm & egg) are produced through meiosis.
Fertilization Occurs – The sperm and egg fuse to form a zygote.
Genetic Variation – Offspring inherit a mix of traits from both parents, leading to diversity.
Common in Multicellular Organisms – Found in humans, animals, and most plants.
Steps of Sexual Reproduction
Gamete Production – Male and female gametes are formed through meiosis.
Fertilization – The sperm and egg unite, forming a zygote.
Zygote Development – The zygote undergoes cell division and develops into an embryo.
Growth & Maturation – The embryo grows into a fully developed organism.
Examples of Sexual Reproduction
Humans – Sperm (male) + Egg (female) → Baby
Animals – Dogs, cats, and birds reproduce sexually.
Plants – Flowering plants use pollen (male) and ovule (female) for reproduction.
Pro Tip: Sexual reproduction ensures genetic diversity, which helps species adapt to environmental changes!
