What must these cells be able to do for this to be possible?
Yeast cells can come in two different mating types. If a cell of one mating type (“male”) is near a cell of the
other mating type (“female”), each one grows a protrusion toward the other. The protrusions meet and fuse,
and the nuclei migrate together, and merge to form a zygote.
