Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If an organism produces offspring without fertilization then it uses
A
Sexual Reproduction
B
Asexual Reproduction
Explanation: 

Detailed explanation-1: -Parthenogenesis. Parthenogenesis is a form of asexual reproduction where an egg develops into a complete individual without being fertilized. The resulting offspring can be either haploid or diploid, depending on the process and the species.

Detailed explanation-2: -Along with not requiring any gametes to fuse, asexual reproduction does not require fertilization or the mixing of genetic material, and meiosis isn’t necessary, which seems to indicate that asexual reproduction saves time and energy!

Detailed explanation-3: -Asexual reproduction generates offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring. Sexual and asexual reproduction have advantages and disadvantages-which is why some organisms do both!

Detailed explanation-4: -Animals that reproduce asexually include planarians, many annelid worms including polychaetes and some oligochaetes, turbellarians and sea stars. Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation, such as gemmae in liverworts.

Detailed explanation-5: -In asexual reproduction, one parent organism produces offspring without meiosis and fertilization. 2. Because the offspring of asexual reproduction inherit all their DNA from one parent, they are genetically identical to each other and their parent.
