Which of the following is an example of alternation of generations? which of the following is an example of alternation of generations? a diploid cell divides by mitosis to produce two diploid daughter cells, which then fuse to produce a tetraploid cell. a haploid mushroom produces gametes by mitosis, and the gametes undergo fertilization, which is immediately followed by meiosis. a diploid animal produces gametes by meiosis, and the gametes undergo fertilization to produce a diploid zygote. a diploid plant (sporophyte) produces, by meiosis, a spore that gives rise to a multicellular, haploid pollen grain (gametophyte).

A diploid plant (sporophyte) produces, by meiosis, a spore that gives rise to a multicellular, haploid pollen grain (gametophyte).

Explanation:

Alternation of generation is a process that occurs in plants and refers to change from sexual haploid to asexual diploid stages and vice versa.

Gametophyte  is haploid stage ( n chromosomes), alternates with a sporophyte, which is diploid ( 2n chromosomes). A mature sporophyte produces spores by meiosis, (reduction cell division) which reduces the number of chromosomes to half, from 2n to n (diploid to haploid).

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
