A Brazilian rainbow boa constrictor kept at a school in England gave birth to 14 babies last ... so she appears to have undergone a natural process of asexual reproduction called parthenogenesis ...
The rainbow boa is typically orange, brown, or reddish brown, with a paler belly and black markings: three parallel stripes on the head, rings down the back, and lateral blotches with a crescent over them, although there is a great deal of natural variation that may be heightened by artificial breeding.
Epicrates maurus is the smallest of the rainbow boas, reaching lengths of 3 to 5 feet on average, [3] although length varies by subspecies. For example, the most common subspecies in captivity is the Colombian rainbow boa (E. m. colombianus) grows to 5–6 feet long and matures between 4–6 years old. There is a clear sexual dimorphism between ...

As of 2017, Booidea contains 61 species, [1] including the eponymous neotropical Boa constrictor, anacondas (genus Eunectes), and smaller tree and rainbow boas (Corallus, Epicrates, and Chilabothrus) as well as several genera of booid snakes from various locations around the world: bevel-nosed boas or keel-scaled boas from New Guinea and ...
A form of asexual reproduction related to parthenogenesis is gynogenesis. Here, offspring are produced by the same mechanism as in parthenogenesis, but with the requirement that the egg merely be stimulated by the presence of sperm in order to develop. However, the sperm cell does not contribute any genetic material to the offspring.
Asexual reproduction in plants occurs in two fundamental forms, vegetative reproduction and agamospermy. [1] Vegetative reproduction involves a vegetative piece of the original plant producing new individuals by budding, tillering , etc. and is distinguished from apomixis , which is a replacement of sexual reproduction, and in some cases ...
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent and thus the newly created individual is genetically and ...
