Reproduction in animals varies from species to species. Some types of reproduction, like parthenogenesis, are more unusual ...

(Mutations do create a minor amount of change.) If asexual reproduction survives at all, conditions must sometimes favor it, even in competition for a niche with sexually reproducing species.

Asexual individuals can pass on their genes twice as fast as those reproducing sexually, because they pass on all their genes -- and only their genes. When reproduction is sexual, half of the ...

Those outlier liaisons gave whiptails robust heterozygosity, which has been preserved by the identical replication—essentially, cloning—that occurs in asexual reproduction. It’s a genetic ...

Imagine a gene that promotes sexual reproduction, such as by making it more likely that a plant will reproduce via sexually produced seeds as opposed to some asexual process (e.g., budding ...

Most likely, sex arose from a combination of all these factors. Asexual reproduction, by contrast, dispenses with the entire business of genetic sorting. Whereas sexually reproducing animals need ...

Plants are able to reproduce in two different ways - sexual reproduction and asexual reproducion. Sexual reproduction involves pollen from one flower fertilising the egg of another to produce a seed.

The finding may offer insight into a long standing question in evolutionary biology about what forces cause species to choose sex over asexual reproduction and vice versa, he said. On paper, ...

Additionally, there is even less asexual representation in film. While a few minor characters in film have been mentioned as being asexual or were later confirmed to be asexual by the creators of the ...

The Amazon molly (Poecilia formosa) is a species of freshwater fish native to Mexico and the southwestern United States. The fish—like their namesake, the mythical Amazonian warriors—are all female.
