So I'm reading Schrodinger's "What is Life", which is very interesting. He says that male drone bees can be considered to be oversized sperm, a phrase that greatly intrigued me. Genetically, there is no distinction between the genes of a sperm cell and those of a male drone bee (although the drone bee has lots of sperm cells, each of which have different genetic material? - is this necessarily the case?) Now, are these male drone bees gametophytes? (just like mosses?) And what of other animals that reproduce through parthenogenesis? They are probably diploid animals though - so they still can be considered sporophytes. Is this correct? Thanks!
