Which yeast group is characterized by symmetrical division?

The yeast group known for symmetrical division is indeed the fission yeast group. Fission yeasts, particularly those belonging to the genus Schizosaccharomyces, reproduce through a process called fission. In this process, the yeast cell divides evenly in half, resulting in two daughter cells that are approximately equal in size. This method of reproduction contrasts with budding yeasts, where a new cell develops as a small protrusion (bud) from the parent cell, leading to daughter cells that are often smaller than the parent cell.

The characteristic symmetrical division in fission yeasts is significant because it allows for a more uniform population in terms of cell size and age, which can have implications for metabolic activities and growth rates. Understanding the different modes of reproduction in yeast is important when studying their biology and applications in fermentation and biotechnology.
