In the alternation of generations life cycle two gametes fuse together to form a. a) gametophyte plant ... b) meiotic division ... c) Zygote ... d) sporophyte.

The correct response would be C. Zygote. Each of the gametes containing half of 50% of the genetic information and or chromosomal content from their respective parents will combine together to essentially produce a diploid chromosome number organism. An organism that would have both complete copies of DNA from each parental organism.
