Assertion : In some species of asteraceae and poaceae seeds are formed without fertilization. Reason : Formation of fruit without fertilization is called parthenocarpy.

Step-by-step solution

Formation of seeds without fertilization is called apomixis. It leads to clonal reproduction in which all offsprings are by and large genetically identical to the parent. The egg contains a full complement of genes and does not need to fuse with a sperm to produce a zygote. Apomixis provides for the perpetuation of traits favourable to individual survival but eliminates the longer-term evolutionary advantage of biparental inheritance. In asteraceae, various genera and individual species of the order asterales are k
