Yeast genetics is the study of genetic variation and inheritance in yeasts, particularly the species Saccharomyces cerevisiae. This research area focuses on understanding the genetic basis of various traits and behaviors in yeast, such as metabolism, growth, and response to environmental conditions. Yeast genetics is also important in biotechnology and molecular biology, as Saccharomyces cerevisiae is a commonly used model organism for studying eukaryotic cell biology and genetics. Studies in yeast genetics have provided insights into gene regulation, protein expression, and the mechanisms underlying genetic diseases.
