|
Fungi tend to reproduce sexually when nutrients are limited or conditions are unfavorable, but reproduce asexually when conditions are ideal, why is this an effective strategy? |
When conditions are favorable, fungi thrives, ther is no reason for it to change the way it reproduces. When conditions are unfavorable, the fungi need to change its growth characteristics. Sexual reproduction creates fungi that are different then its parent. |
