Vedclass · Answer

(D) Apogamy is the development of a sporophyte directly from the gametophyte cells without the fusion of gametes (fertilization). Since the sporophyte is formed directly from the gametophyte tissue,it retains the ploidy level of the gametophyte. Therefore,a tetraploid gametophyte would produce a tetraploid sporophyte,not the other way around. Thus,the Assertion is incorrect. Reasoning: Apogamy is a type of apomixis where the sporophyte develops without fertilization. Since fertilization is absent,the Reason statement is also incorrect because it implies apogamy involves fertilization.

$A$ : Tetraploid gametophyte can be produced from tetraploid sporophyte by means of apogamy. $R$ : Apogamy involves fertilisation,not meiosis.
