What do you mean by plasmogamy??

reproduction stage of fungai

Plasmogamy is the stage in the sexual reproduction of fungi, in which the plotoplasm of two different cells, fuses together with the fusion of nuclei effectively bringing two haploid nuclei close together in the same cell.

Plasmogamy is the fusion of two hyphal protoplast.

Thanks

a and c are the answeres

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
