Asexual Reproduc tion

What is asexual reproduc tion?

‣ In asexual reproduction, one parent organism

produces offspring without meiosis and fertilization.

‣ Offspring produced by asexual reproduction inherit

all of their DNA from one parent. Therefore, they are genetically the same as each other and their parent.

What is asexual reproduc tion?

‣ You have seen the results of asexual reproduction

if you have ever seen mold on bread or fruit.

‣ Mold is a type of fungus that can reproduce either

sexually or asexually.

What is asexual reproduc tion?

‣ Asexual reproduction is different from sexual

reproduction.

‣ Remember that sexual reproduction involves two

parent organisms and the processes of meiosis and fertilization. Offspring inherit half of their DNA from each parent, resulting in genetic variation among the offspring.

Who reproduces asexually?

‣ There are many different types of organisms that

reproduce asexually.

‣ Not only fungi, but also bacteria, protists, plants,

and animals can reproduce asexually.

‣ Prokaryotic cells, such as a

bacterial cell, have a simpler cell structure than a eukaryotic cell.

‣ A prokaryote’s DNA is not

contained in a nucleus. For this reason, mitosis does not occur.

‣ Remember, what is the

definition of mitosis?

‣ Cell division in a prokaryote is

a simpler process than in a eukaryote.

‣ Cell division in prokaryotes that

forms two genetically identical cells is known as fission.
