This discussion on What is haplontic and diplontic life cycle?
About the Author: A life cycle is a period involving one generation of an organism through means of reproduction, whether through asexual reproduction or sexual reproduction. Some lichen, however, such as Lobaria scrobiculata, have a unique feature: This ensures that the gametes will have only one set of chromosomes, so when they fuse again during sexual reproduction, the resulting zygote will have the two sets of chromosomes of a normal diploid cell.

These three types of cycles feature alternating haploid and diploid phases n and 2n. The cycles differ in the product of meiosis, and whether mitosis growth occurs.Haplontic Diplontic Life Cycle
This results in a zygote which then germinates. A new study places value on indigenous and local knowledge contribution in the...

One of the gametes comes from a female and the other from the male. This continues on for the organism's entire life cycle.
Why do I need to sign in? This allows a nice mixture of the genetics of both parents and increases diversity of traits in the gene pool for natural selection to work on.
Upvote 2. The haplontic life cycle consists of a free-living gametophyte while the diplontic life cycle consists of a free-living sporophyte in plants. Some species use asexual reproduction to make offspring, while others reproduce using sexual reproduction. Fertilization of the gametes produces the next generation.

Like the haplontic and diplontic life cycles, organisms that have an alternation of generations sexual life cycle begin life as a diploid zygote formed from the fusion of haploid gametes from a male and a female.
