ASEXUAL REPRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which reproduction requires a mate?
A
asexual
B
sexual
C
neither
Explanation: 

Detailed explanation-1: -Sexual reproduction requires two parents. Each parent contributes a gamete-a sex cell that has half of the normal DNA of a regular body cell. In males, the gametes are sperm and in females, the gametes are eggs.

Detailed explanation-2: -Unlike in sexual reproduction wherein male and female gametes unite to reproduce offspring, in asexual reproduction, this union is not necessary. The organism can reproduce in the absence of a mate in which, in this case, produces offspring which is usually a clone of the parent.

Detailed explanation-3: -Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.

Detailed explanation-4: -There are different types of asexual reproduction: Binary Fission. Budding. Fragmentation.

Detailed explanation-5: -Asexual reproduction occurs by cell division during mitosis to produce two or more genetically identical offspring. Sexual reproduction occurs by the release of haploid gametes (e.g., sperm and egg cells) that fuse to produce a zygote with genetic characteristics contributed by both of the parent organisms.
