I NEED HELP ASAP (WILL MARK BRAINLIEST IF ITS THE RIGHT ANSWER) which of the following describes asexual reproduction
Mekhanik [1.2K]

<em>B. One parent organism and no egg or sperm.</em>

Explanation:

In asexual reproduction, an organism can produce offspring with no gametes involved (eggs or sperm), and does not need to undergo meiosis.

If an organism produces offspring through asexual reproduction, all of the DNA from the parent will go to the offspring. Since there is only one parent, meiosis will not occur since there is no need for genetic differentiation.

All of the organisms produced by the parent during asexual reproduction will be identical to the parent. They will have the same DNA and genetic make up.
