- What Is Asexual Reproduction | Genetics | Biology | FuseSchool
Asexual reproduction only needs one parent; all the offspring are clones. This means they are genetically identical to one another and to the parent.
Many plants use asexual reproduction, like spider plants. Bacteria also reproduce asexually in a process called binary fission. And even some animals use asexual reproduction. It is much less common, but is seen in some simple ones like Hydra, Aphids and starfish.
Asexual reproduction does not involve sex cells or fertilisation. Asexual reproduction occurs using normal cell division known as mitosis.
One major advantage of asexual reproduction is that populations can increase rapidly. They don’t have to waste time and energy in finding a mate. Also by being clones, they can exploit a suitable habitat quickly. They fill the niches, making it harder for predators and competitors to invade.
However, it also comes with disadvantages. There is no genetic variation; if the climate or selection pressures change then the population will be much slower to adapt as they have no diversity. By being identical, the population is best suited to only that one habitat and all have the same vulnerability to disease. The same traits also mean the same weaknesses. If a predator or disease adapts to kill one individual, then they can take out the entire population, resulting in extinction. Genetic variation does have a lot of merits.
Some organisms can combine both sexual and asexual reproduction depending upon the circumstances. Malarial parasites reproduce asexually in the human host, but sexually in the mosquito. Many fungi reproduce asexually by spores but also reproduce sexually to give variation. And many plants produce seeds sexually, but also reproduce asexually by runners such as strawberry plants, or bulb division such as daffodils. Even aphids alternate between sexual and asexual reproduction - asexually in the spring and summer, and then sexually in the winter as the eggs can survive the cold better.

What are the advantages and disadvantages for asexual reproduction
my assignment is to list all possible genotypes of a offspring of a parent that has genotype AaEeNn. Wouldnt it just be AaEeNn since offsprings dna is identical? but it also implies there should be multiple answers so i am so confused and any help is great.
This video might help: czcams.com/video/BRMcTdKNpOA/video.html
I have to Watch this for school because a quiz i was assigned this
Thank you
Ill say welcome for u
Good
you are amazing
i hope that you would get 1m subs
Thank you so much ❤️

Try turning on subtitles or watch in .75 speed or something
very good video i also learned about this
Glad to hear that!
Is it fast or slow
you are explaining very fast so hope you slow down in other vids
Noted!
Does plant cutting, grafting or layering do asexually reproduction because it is made by man and I can't i dentify if it's asexually reproducing.
You talk waaaaay too fast!
Slow down the video
Nadia Heredia lol
Ûr jüśt šłøw iñ thë hęäd
i had to slow down the video like srsly he talks faster than the speed of light
Oh sheat
A very good class but too fast
ty
No worries!
What about a certain plantlet or tubers do they reproduct asexually?
it goes through so fast and i can't understand what he is saying
@ watch this about the difference of sexual and asexual reproduction. A video which makes you easily understand concepts related to reproduction.
Please , can you guys have English subtitles ?
Useful content, but you talk too fast.
gotta love when school teaches me how i reproduce... (i'm asexual if you didn't get the joke)
I am sexual and i need females to reproduce gamete
Wtf is the joke
Okay that doesn’t make sense because humans can’t be asexual. That is just another made up thing.
SaMe
oh thats just stupid
turn off one of your mics, one is in my left ear and the other is in my right
nice video
Thanks!
All is nice but Audio Voice is some what echo
what application dude?
After Effects
Write each of the names of plant which reproduces asexually by root and leaf.
Can you let me know what is " ATHENS" ? I'm preparing for my report and i can't understand its meaning of " ATHENS "!!! Thanks for helping!
Aphids
I think you mean Aphids? Check the transcript in the description.
It's a city in Greece Ur report is probably over but anywwy
Do you mean aphids?
It's "aphids" actually ;-)
I like the video 😃
Thanks!
Forgot the question mark.
so what does mean ?!
Sir,
Does asexual reproduction only takes place in females?
Pls answer
You probably mean parthenogenesis - one of the forms of asexual reproduction. It's when an egg can develop into an embryo without being fertilised by a sperm. Several insect species including aphids, bees, and ants are known to reproduce by parthenogenesis. In animal world, it essentially makes it possible for females to reproduce without males.
POV: You're watching this in class for some reason
here from school
Do trees have feelings?
idk but i think because one someone will cutted the tree or their part of their body they will be hurt Animals have feelings Human Have feelings Trees have feelings too all of us have feelings...
how many tipes of asexual reproduction are presented in the video xd tell my pl
i ship P=B
Brynlie (me)and peyton(my crush)
K

Sexual reproduction occurs by meiosis
Study well about all things then teach us
@Yunushkan pathan Yeah I saw that too!

Dude the talking sounded like it's being generated. Am I listening to a robot? I don't need to waste time analyzing what you're murmuring about
