Which best describes the alternation of generations? Fertilization produces haploid spores. Meiosis produces a diploid zygote. A gametophyte is its diploid phase. A gametophyte is its haploid phase.

A gametophyte is its haploid phase.

Explanation:

The statement that best-described alternation of generation would that a gametophyte is a haploid phase.

Alternation of generation is a type of life cycle that involves alternating between the diploid (2n) and the haploid phase of the same organism. The haploid gametophyte produces the male and female gametes that fuse together to form a diploid zygote during fertilization.

The zygote divides mitotically to give the diploid sporophyte. The latter undergo meiosis to produce haploid spores which then germinates to give rise to haploid gametophytes and the cycle is repeated.
