Answer:
c haploid gamete cells
Step-by-step explanation:
The vast majority of cells in the body are diploid, meaning they have two copies of every chromosome. However, like the question says, if during fertilization, the diploid cells fuse, then there will be 4x copies of every chromosome in the first generation, 8 in the second, and so on.
Meiosis creates haploid cells from diploid cells through one round of DNA replication and then two cell divisions to create haploid cells, one copy of each chromosome.
During fertilisation, when the gametes fuse, they make a diploid cell that develops into a new organism.
