In asexual reproduction, the offspring come from a single parent, so no copulation occurs, and only one organism is responsible for the reproduction. In sexual reproduction, on the other hand, two organisms conceive or bear the offspring.Know More
Asexual reproduction is the main mode of reproduction of certain types of organisms, such as bacterias, protists and archaea. The simple cell division is the basis for asexual reproduction. The nucleus in the cell divides into two and chromosomes in the original nucleus are copied so that one half gets the same exact DNA as the original cell, resulting in both halves becoming identical. Daughter cells are formed, and these daughter cells further divide. Asexual reproduction essentially creates a clone of the parent, as no other factor alters the genes or DNA of the parent.
In sexual reproduction, two types of cells are involved: the egg cell and the sperm cell. Unlike asexual reproduction, the offspring cannot be clones because two organisms are involved in this process. The offspring has its own genetic make-up, so it is unique, in a biological sense. In an evolutionary sense, while sexual reproduction is more complex, it ensures a certain amount of diversity thanks to the continuous melding and mixing of genes.Learn more in Animal Reproduction
The primary disadvantage to asexual reproduction is the lack of genetic diversity among the resulting offspring. In contrast to sexual reproduction, which involves the recombination of two different sets of genes, an asexual organism possesses the same genes as its parent did. This can lead to problems if the parent has a genetic defect; without another parent to replace the gene, the offspring possesses the defect as well.Full Answer >
Spaying and neutering are both procedures used to sterilize animals like dogs and cats, but spaying refers to the procedure done to female animals while neutering is the corresponding process for males. Spaying involves taking out the uterus and ovaries while male pets are neutered by taking out the testicles.Full Answer >
Fertility is the natural capacity to produce offspring, whereas fecundity is the potential capacity for reproduction, according to Biology Online. Although the terms are often used interchangeably in common language, the Geneva Foundation for Medical Education and Research explains how they take on very distinct meanings when discussing matters of demographics and human population trends.Full Answer >
Frogs are not asexual. The amphibians reproduce through external egg fertilization which happens in or very close to water. The length of time between fertilization and hatching varies by species and takes between six and 21 days.Full Answer >
