The life cycle of animals
A) demonstrates alternation of generations, where the zygote is haploid and the adult is diploid.
B) does not demonstrate alternation of generations. Both the zygote and the adult are haploid.
C) demonstrates alternation of generations, where the zygote is diploid and the adult is haploid.
D) does not demonstrate alternation of generations because only the spores are haploid.
E) does not demonstrate alternation of generations; gametes are haploid and the organism is diploid.
Alternation of Generations
A reproductive cycle found in plants and some algae, involving both asexual and sexual phases.
Haploid
Having a single set of unpaired chromosomes, a condition typical of gametes in sexually reproducing organisms.
Diploid
Referring to a cell or organism that has two sets of chromosomes, one set inherited from each parent.

Final Answer :
E
Explanation :
In the life cycle of animals, there is no alternation of generations as seen in some plants and algae. Instead, animals produce haploid gametes through meiosis, which then fuse during fertilization to form a diploid zygote. The zygote grows into a diploid adult organism. This process does not involve a haploid adult stage or a multicellular haploid phase, distinguishing it from the true alternation of generations.
