Heterochromia is a variation in coloration most often used to describe color differences of the iris, but can also be applied to color variation of hair [1] or skin. Heterochromia is determined by the production, delivery, and concentration of melanin (a pigment). It may be inherited, or caused by genetic mosaicism, chimerism, disease, or ...
A genetic chimerism or chimera (/ k aɪ ˈ m ɪər ə / ky-MEER-ə or / k ɪ ˈ m ɪər ə / kim-EER-ə) is a single organism composed of cells with more than one distinct genotype. Animal chimeras can be produced by the fusion of two (or more) embryos .
A chimera can have two different colored eyes just like any two siblings can—because each cell has different eye color genes. A mosaic can have two different colored eyes if the DNA difference happens to be in an eye-color gene. There are many other possible reasons for having two different-colored eyes.
A human chimera is a human with a subset of cells with a distinct genotype than other cells, that is, having genetic chimerism.In contrast, an individual where each cell contains genetic material from a human and an animal is called a human–animal hybrid, while an organism that contains a mixture of human and non-human cells would be a human-animal chimera.
Physically, the different genes manifest through coat color and eye color." They go on to add, that just because a cat has two distinct colors doesn't make them chimera. Interestingly, this unique ...
Cat coat genetics is a complicated issue, as the color of a cat’s coat is controlled by several different genes, some which are linked to the sex of the cat and some which are not.
In molecular biology, and more importantly high-throughput DNA sequencing, a chimera is a single DNA sequence originating when multiple transcripts or DNA sequences get joined. Chimeras can be considered artifacts and be filtered out from the data during processing [ 1 ] to prevent spurious inferences of biological variation. [ 2 ]
The reason boils down to genes. A senior lecturer in biomolecular sciences at Liverpool John Moores University said, "What we know now is that eye color is based on 12 to 13 individual variations ...
