Yes, it is observed in parthenocarpic fruits. The ‘seedless fruits’ that are available in the market such as pomegranate, grapes etc., are infact good examples.

hormone that induces fruit development even though fertilisation has not occurred. The ovules of such fruits, however, fail to develop
into seeds.
Both angiosperms and vertebrates have a more complex structural organisation. They have evolved very efficient mechanism of sexual reproduction. Since asexual reproduction does not create new genetic pools in the offspring and consequently hampers their adapability to external conditions, these grouRead more
