That is an interesting question because it overlaps the question of why animals still reproduce sexually when asexual reproduction is genetically twice as favourable to the parent. The short answer to that appears to be that over the long term (t...

Can parthenogenesis occur in humans? Well, I am only a sudent and what i know about this is that apart from going into deep irrational beliefs of christianity the birth of Jesus christ depicted ...

en.wikipedia.org/wiki/Parthenogenesis

Parthenogenesis can occur without meiosis through mitotic oogenesis. This is called apomictic parthenogenesis. Mature egg cells are produced by mitotic divisions, and these cells directly develop into embryos. In flowering plants, cells of the gametophyte can undergo this process.

Parthenogenesis is possible in humans but very unlikely to result in a viable baby. In order for an embryo to develop from an unfertilized egg, the egg would have to sense a spike in calcium, skip meiosis and then lose at least two specific maternal genes.

Parthenogenesis can occur without meiosis through mitotic oogenesis. This is called apomictic parthenogenesis. Mature egg cells are produced by mitotic divisions, and these cells directly develop into embryos. The offspring produced by apomictic parthenogenesis are full clones of their mother.

Parthenogenesis in humans may seem far-fetched, but 50 years ago no-one suspected that parthenogenesis could occur in any vertebrate: now all-female species have been documented in fish, amphibians, reptiles and birds (all major orders of vertebrates except mammals). In the mid-1950's, the British medical journal Lancet published an

Parthenogenesis is an adaptive strategy to ensure the reproduction of organisms when conditions are not favorable for sexual reproduction. Asexual reproduction can be advantageous to organisms that must remain in a particular environment and in places where mates are scarce.

Best Answer: Parthenogenesis doesn't occur in humans (or any mammal naturally), but there are probably some scientists out there considering it in labs. The reason why its not experimentally done with humans is because its probably unethical. But on top of that, our species has males to rely on for creating ...

Parthenogenesis can occur in human females. If a certain series of hormones is triggered, evan in the abstance of sperm an egg can still start developing. It is only hapliod, but it develops into a tumor that has hair and teeth. Freaky!

Scientists estimate that imprinting affects about 200 different genes. For parthenogenesis to occur, many of these changes would have to occur through random mutation.
