In humans, gametes are always haploid, 2 haploid gametes fuse during fertilisation to form a diploid zygote. Haploid means half the chromosomes (23 in humans), and this is always the case as meiosis only takes half the chromosomes for each gamete, unlike mitosis which creates a genetically identical cell each time (the process that occurs for other cells in your body).
Gametes are normally haploid, meaning they contain half the chromosome number of diploid body cells. This is crucial for fertilization, as it allows two haploid gametes to combine and form a diploid zygote. Therefore, the correct answer is A. haploid .
