Question

some fungi are able to reproduce both sexually and asexually. which of the following describes a consequence that would most likely occur if fungi undergo only sexual reproduction for a long period of time?

the species would eventually become unable to reproduce asexually, but diversity would increase
there would be gradual reduction in genetic diversity, but the overall population would rise
the frequency of genetic mutations would increase, but reproduction rates would lower
the species' life span would begin to decrease, but reproduction rates would stay constant
