In a typical alternation of generations life cycle, the zygote develops into a sporophyte, which is diploid (2n), meaning it has the same chromosome number as the zygote. The gametophyte is haploid (n), having half the chromosome number of the sporophyte. Therefore, if the zygote has ten chromosomes, the sporophyte will also have ten, and the gametophyte will have five.
