Baker’s yeast is a tiny, single-celled fungus that makes bread dough rise and converts sugars in alcohol. This yeast reproduces by budding. As the small bud grows, it receives a copy of the parent’s nucleus. When the bud pinches off, the new cell is smaller than the parent cell but genetically identical  What type of reproduction is this?
