Apomixis: Asexual Seeds — NEET Biology
✅ Asked in NEET 2019Although seeds, in general are the products of fertilisation, a few flowering plants such as some species of Asteraceae and grasses, have evolved a special mechanism, to produce seeds without fertilisation, called apomixis. What is fruit production without fertilisation called? Thus, apomixis is a form of asexual reproduction that mimics sexual reproduction. There are several ways of development of apomictic seeds. In some species, the diploid egg cell is formed without reduction division and develops into the embryo without fertilisation. More often, as in many Citrus and Mango
Apomixis is asexual seed production where a diploid egg cell develops into an embryo without fertilization or meiosis, yet produces seeds that look like sexual reproduction. Students often confuse apomixis with parthenogenesis or incorrectly think it requires pollination. The key distinction: apomixis produces seeds (with seed coat and endosperm) without fertilization, while the embryo develops directly from the diploid egg. NEET repeatedly tests whether you recognize that apomixis is truly asexual reproduction mimicking sexual reproduction—it bypasses meiosis entirely, making it genetically identical to the parent unlike sexual reproduction.
