In sexual reproduction, two different strains of hyphae called PLUS and MINUS strains fuse nuclei and produce a zygote.
Sex chromosomes determine the sex of an organism. The different sexes are listed as either the plus strain or the minus strain. Both the strains fuse their nuclei and produce a zygote.
Option c- plus, minus
+ and -
Sexual reproduction occurs when the hyphae of two different strains meet and merge. For this to happen the two strains must be compatible, they are designated as + and -.
When these are found, two cells are formed in the apical region that are called gametangios, one of them contains + nuclei and the other -, when fused they will form diploid nuclei that will produce the zygote.
