Answer:
Sharp-spined cactus
Explanation:
Given, that N allele is required for the production of spine and S allele will produce sharp sines.
True breeding sharp spined cactus: NNSS
spineless cactus: nn__ ( we can't fix the allele for second gene since it has not been mentioned as true breeding )
Their progeny: NNSS X nn__ = NnS_
So the progeny is going to be sharp spined because both the dominant alleles N and S are present.
No one knows. There's no confirmation date at the moment. As that comment said, only time will tell.
It is Prophase.
Hoped this helped.
