Advantages of Heterospory:
1. In heterosporous forms, the endosporic gametophytes are independent of external conditions and self-supportive in food supply. Thus, the female gametophyte that developed within the large megaspore, at the expense of reserver food, is in a better situation for the initiation of embryo. Whereas, the free-living exosporic gametophytes of homosporous members are totally dependent on external conditions.
2. Heterospory induces a drastic reduction in the sizes of their gametophytes. There is an extreme reduction in the male gametophyte and, in most cases, it is nothing but an antheridium. The female gametophyte never outgrows the limits of the megaspore.
3. In heterosporous forms the differentiation of sex can be predicted at the spore stages. Thus the sex differentiation can be extended from the early stage of gametophyte to the sporophyte.

The answer of u r question is..✌️✌️
Advantage of heterospory:
☺️The phenomenon of heterospory is of a great biological advantage because of the fact that a large magaspore which contain female hamate derives it food from sporophyte.
☺️It is independent of external condition.
Hope it helps uu!!⭕️⭕️
Thank you..⭐️⭐️
