In meiosis, what is a fertilized cell known as? How many chromosomes exist after fertilization?

answer; the correct answer is desert plants;

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.
