Dredd has been an asexual character since his introduction in the second issue of 2000 AD (1977).
But it is only by looking at an asexual group that the second can be tested independently of the first.
That term could also include the 1% of people who identify as asexual, which means they aren't sexually attracted to anyone.
An asexual female who clones herself ten times is like someone who buys ten raffle tickets, each with the same number.
In asexual animals or plants, evolutionary diversification is much slower because of the lack of genetic remixing that happens during sex.
This colony is not the only known example of an asexual ant.
Many biologists, therefore, have suspected that, although they appear to be asexual, they occasionally sneak off for a quick one when nobody is looking.
But asexual ants of other species either rely on one or a few individuals to lay eggs, or else only the younger ants do it.
Yes, there are corseted shapes in this exhibit, but more mysterious are the brooding, woolen capes and shrouds, which are protective, asexual rooms, so to speak, of one's own.

Persuasive evidence against this, and in favor of the idea that they are harmful parasites that generate greater evolvability only as a side effect, comes from asexual species.
However, I'm asexual - I'm not sexually attracted to anyone.
Instead as shown by some tiny animals, called rotifers, that have not had sex for 80 million years selfish DNA is generally purged from the genomes of asexual species as a nuisance.
However, one young researcher, who investigated the effects of light on asexual reproduction of planaria (flatworms), described what it was like to learn during the course of his experimentation that his hypothesis was wrong.
And because chromosomes and therefore genes come in pairs, and mutations occur independently in each gene of the pair, the two versions of a particular gene in any asexual line will gradually diverge, becoming more and more different from one another.
And knowing the rate at which neutral mutations accumulate in most animal species, the 50% figure suggests that the first asexual rotifer lived about 80m years ago twice as far back as the oldest known fossil bdelloid, a 40m-year-old specimen preserved in amber.
The group adds that the draft curriculum does not mention reproduction again until the end of primary school when the guidance for teaching 10 and 11-year-olds says "they should find out about different types of reproduction, including sexual and asexual reproduction in plants, and sexual reproduction in animals".
