Mutation in animals wikipedia
The resulting dispermic chimera has distinct DNA in different tissues, for example, a liver arising from one cell population and kidneys arising from the other. In animals, an easily observable examples of chimerism is a patchwork coloration of skin, hair, fur, and even the iris of the eyes.Evolution is a scientific theory used by biologists. The human ability to drink milk during adult life is supported by a lactase mutation which prevents this switchoff. One of the most widespread adaptations in animals is the evolution of the eye. mutation in animals wikipedia
When people talk about mutation rates per animal they are usually talking about germ cell mutation rates, as these are the ones that get inherited and thus impact evolution. To a first aproximation, the germ cell mutation rate in all animals is about the same.
Genetic engineering has many applications to medicine that include the manufacturing of drugs, creation of model animals that mimic human conditions and gene therapy. One of the earliest uses of genetic engineering was to massproduce human insulin in bacteria. Myostatin is a secreted growth differentiation factor that is a member of the TGF beta protein family. Animals either lacking myostatin or treated with substances that block the activity of myostatin have significantly more muscle mass.mutation in animals wikipedia Genetic variation is brought about, fundamentally, by mutation, which is a permanent change in the chemical structure of chromosomes. Genetic recombination also
