Answer:
Haploid cells join to form an organism that has a complete set of chromosomes is the correct answer.
Step-by-step explanation:
In the fertilization process two haploid cells sperm fuse with an egg which results in the formation of a diploid cell.
meiosis produces haploid cells rather than diploid cells because in Meiosis the chromosome number gets reduced.
In the Meiosis process the number of chromosomes in the daughter cells gets reduced to half than of the parent cell and this process results in the formation of four haploid daughter cells
Thus Haploid cells join to form an organism that has a complete set of chromosomes is the correct answer.
