a definite process of this cycle. Letter A marks a process of spore germination. Letter B marks a process of cytoplasm fusion. Letter C marks fusion of nuclei and formation of a round solid structure. Letter D marks a process by which the round solid structure produces spores. Letter E marks the other cycle, by which mycelium is formed from the spores. The process indicated by the letter _____ produces a diploid structure. A life cycle of the black bread mold.

Cytogamy, in animals and in lower plants, indicates the fusion of two gametic cells (n). Thus, their genetic material (the two nuclei) will be in the same cytoplasm, and so we will have a set of two chromosomes (2n) in a cell, and this is the definition of a diploid cell.
Then the two nuclei will merge (karyogamy) to give the zygote, which will eventually give a new species.
Traits are inherited trough the parents genes that are passed to the offspring trough both parents reproductive cells, that contain genes in their nucleus.
