  2. List of organisms by chromosome count - Wikipedia

    en.wikipedia.org/wiki/List_of_organisms_by...

    The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms. This number, along with the visual appearance of the chromosome, is known as the karyotype , [ 1 ] [ 2 ] [ 3 ] and can be found by looking at the chromosomes through a microscope .

    en.wikipedia.org/wiki/Orangutan

    The name "orangutan" (also written orang-utan, orang utan, orangutang, and ourang-outang [1]) is derived from the Malay words orang, meaning "person", and hutan, meaning "forest". [ 2 ] [ 3 ] The locals originally used the term for actual forest-dwelling humans, but the word underwent a semantic extension to include apes of the Pongo genus at ...

    en.wikipedia.org/wiki/List_of_hominoids

    Sumatran orangutan (Pongo abelli) Hominoidea is a superfamily of primates. Members of this superfamily are called hominoids or apes, and include gorillas, chimpanzees, orangutans, gibbons, bonobos, and humans. Hominoidea is one of the six major groups in the order Primates. The majority are found in forests in Southeastern Asia and Equatorial Africa, with the exception of humans, which have ...

    en.wikipedia.org/wiki/Sumatran_orangutan

    An orangutan will break off a tree branch that is about a foot long, snap off the twigs and fray one end with its teeth. [10] The orangutan will use the stick to dig in tree holes for termites. They will also use the stick to poke a bee's nest wall, move it around and catch the honey. In addition, orangutans use tools to eat fruit. [11]

    The human genome has been sequenced, as well as the chimpanzee genome. Humans have 23 pairs of chromosomes, while chimpanzees, gorillas and orangutans have 24. Human chromosome 2 is a fusion of two chromosomes 2a and 2b that remained separate in the other primates. [9]

  7. Bornean orangutan - Wikipedia

    en.wikipedia.org/wiki/Bornean_orangutan

    The Bornean orangutan and the Sumatran orangutan diverged about 400,000 years ago, [4] with a continued low level of gene flow between them since then. [4] The two orangutan species were considered merely subspecies until 1996; they were elevated to species following sequencing of their mitochondrial DNA. The Bornean orangutan has three ...

  8. Karyotype - Wikipedia

    en.wikipedia.org/wiki/Karyotype

    The basic number of chromosomes in the somatic cells of an individual or a species is called the somatic number and is designated 2n. In the germ-line (the sex cells) the chromosome number is n (humans: n = 23). [4] [5] p28 Thus, in humans 2n = 46. So, in normal diploid organisms, autosomal chromosomes are present in two copies.
