Yeast can reproduce sexually through a signaling pathway known as the mating factor pathway. In this process, two haploid yeast cells combine to form a diploid cell. Yeast cells secrete a signal molecule called mating factor that attracts them to their mates. Once the mating factor of one yeast binds to the receptor on another yeast, an outgrowth called a "shmoo" forms, which allows the yeast cells to fuse together.
