The spores will be haploid and have five chromosomes per cell , if the number of chromosomes in a diploid nucleus is 10.
In most fungi the zygote is the only cell in the entire life cycle that is diploid. In life cycle of a sexually reproducing fungus, a haploid phase diploid phase alternate with each other. The diploid cell resulting from fusion of two haploid sex cells .
Sexual reproduction is important part in all fungi. This involves mating between two haploid hyphae. During mating, two haploid parent cells fuse, forming a diploid spore called a zygospore. Diploid sporophyte cells undergo meiosis to produce haploid spores, and the cycle continues .
