In fungal sexual reproduction,

a.) plasmogamy occurs before karyogamy.

b.) karyogamy begins after fertilization.

c.) karyogamy creates diploid spores.

d.) zygotes are haploid.

e.) spores are hapliod

f.) plasmogamy produces heterokaryotic cells.

Step 1: Plasmogamy occurs before karyogamy

Step 2: plasmogamy produces heterokaryotic cells

Step 3: karyogamy begins after fertilization.

Step 4: karyogamy creates diploid spores.

Step 5: Zygotes produces haploid

Step 6: Spores forms from haploid

Explanation:

Karyogamy is the last step in the cycle of fusing together two haploid eukaryotic cells and refers specifically to the fusion of the two nuclei. Ahead of karyogamy, each haploid cell has one finished copy of the organism's genome. In order for karyogamy to occur, the cell membrane and cytoplasm of each cell must fuse with the other in a process known as plasmogamy. Once within the joined cell membrane, the nuclei are referred to as pronuclei. Once the cell membranes, cytoplasm, and pronuclei fuse together, the resulting single cell is diploid, containing two copies of the genome. This diploid cell, called a zygote or zygospore can then enter meiosis (a process of chromosome duplication, recombination, and division, to produce four new haploid cells), or continue to divide by mitosis. Mammalian fertilization uses a comparable process to combine haploid sperm and egg cells (gametes) to develop a diploid fertilized egg.
