Consider the diagram of reproduction of yeast cells. yeast can reproduce both asexually and sexually. During sexual reproduction, alpha or a cells produce ‘a-factor’, which signals the presence of an a cell to neighboring a cells and the a cells also respond to a factor. Each cell grows a projection towards the opposite cells and this response of haploid cells to the mating factors of the opposite mating type allows for conjugation between a and a cells, but not between cells of the same mating type. What is the advantage to this type of reproduction?
