Question

which of the following is an example of asexual reproduction?
a binary fission in bacteria
b spore formation in fungi
c mating in mammals
d fertilization in frogs
e pollination in plants

Explanation:

Asexual reproduction involves a single parent and offspring with the same genetic material. Binary fission in bacteria (a) is when one bacterium splits into two identical cells, requiring one parent. Spore formation in fungi (b) also produces spores from a single parent. Mating in mammals (c), fertilization in frogs (d), and pollination in plants (e) involve two parents (sexual reproduction), so they are not asexual. Both a and b are asexual, but if we consider typical examples, binary fission in bacteria is a classic asexual reproduction example, and spore formation in fungi is also asexual. However, the question asks for an example, and both a and b are correct, but let's check the options. Wait, the options: a is binary fission (bacteria), b is spore formation (fungi). Both are asexual. But maybe the question expects one? Wait, the problem says "which of the following", so multiple correct? But maybe in the context, a and b are correct. Wait, let's recheck:

• Binary fission in bacteria: asexual (one parent, splits into two, identical).
• Spore formation in fungi: asexual (spores are produced by a single parent, grow into new organisms).
• Mating in mammals: sexual (two parents, gametes fuse).
• Fertilization in frogs: sexual (sperm and egg from two parents).
• Pollination in plants: sexual (involves male and female gametes, often from different plants or same plant but different flowers, sexual reproduction).

So both a and b are examples of asexual reproduction. But maybe the question has multiple correct answers? But the options are a, b, c, d, e. So if we have to choose, both a and b are correct. But maybe the intended answers are a and b. Wait, but let's see the options. Let's confirm:

Asexual reproduction methods include binary fission, spore formation, budding, fragmentation, etc. So binary fission (bacteria) and spore formation (fungi) are asexual. So the correct options are a. Binary fission in bacteria and b. Spore formation in fungi.

Answer:

a. Binary fission in bacteria, b. Spore formation in fungi
