How does apomixis differ from sexual reproduction?

📌 CONCEPT: Apomixis is a process of seed production in plants that lacks fertilization, yet still produces viable seeds.

📐 RULE / FORMULA: Apomixis differs from sexual reproduction in the absence of gamete fusion, resulting in a parthenogenetic mode of reproduction.

💡 WORKED EXAMPLE: A plant exhibiting apomictic seed production is a local population of a grass species. In this scenario, seeds are produced without fertilization, showcasing apomixis. For instance, the Dandelion (Taraxacum officinale) is an example of a plant that exhibits apomixis, producing seeds without the involvement of gametes.

⚠️ COMMON MISTAKE: Students often confuse apomixis with parthenogenesis, but apomixis is a broader concept that includes various mechanisms for seed production without fertilization, whereas parthenogenesis is a specific process where an egg develops into an individual without fertilization.
