Reproduction is the fundamental feature to all living life. Each organism on earth exist due to reproduction, rather it’s through asexual or sexual reproduction.
There are two main types of reproduction, sexual and asexual. There are many plants, animals, insects, bacteria, fungi that are asexual and reproduce without any mate. Asexual reproduction is when the individual produces the offspring and the offspring is more identical to itself. The offsprings are reproduced by mitosis. Below are 4 animals that are asexual.
- Whiptail Lizard
Whiptails liazrds are cross breeds between which could be the reason why they have several chromosomes. They don’t need any make chromosomes to reproduce healthy eggs and offspring’s. It is said that these whiptail lizards are freak because before laying eggs they start to mount other lizards. Pseudosexual behavior is well known among uni-sexual lizards.
2. Komodo Dragon
The female Komodo Dragon can lay eggs that turn into healthy offspring’s without having sex with a male Komodo Dragon counterpart. This was just recently discovered by scientist in 2006 when they noticed a female Komodo Dragon named Flora living in a zoo who laid healthy eggs without ever been exposed to a male Komodo Dragon. Furthermore, Female Komodo Dragons have two sex chromosomes, a Z and W unlike the male dragon who has ZZ chromosomes.
3. Marmorkrebs Crayfish
Back in 2003 there was an experiment done by biologist reported by TIME Magazine on a female marmorkrebs crayfish. The biologist stated the Female Crayfish was in a aquarium by herself and ended up laying multiple eggs that developed into her offspring. The scientist looked heavily for sperm or male gonads that could have been hiding in her cavity’s so that she would be able to fertilize the eggs, but they found nothing.
4. Hammer Head Sharks
In 2007 researchers found a female shovel-head that had not been exposed to any male hammer heads had laid eggs with a full set of chromosomes that had been doubled by her female genetics. This is a process called automatic parthenogenesis.
