Analogy: A similarity due to convergent evolution (common function) but not due to having a common ancestor (bat's wings and bird's wings). See also homology.

The similarity of structure between two species that are not closely related; attributable to convergent evolution.

The rows of lock boxes in a bank provide a useful analogy.

An analogy between ATP and rechargeable batteries is appropriate. The batteries are used, giving up their potential energy until it has all been converted into kinetic energy and heat/unusable energy.
An analogy which is sometimes useful is to suppose a mixture of bees and wasps passing over a flower bed. The bees would be more attracted to the flowers than the wasps, and would become separated from them.
As an analogy to the techniques we use, consider how an alien species might try to find, for example, the New York Knicks basketball team. Upon arriving in the solar system, they would first learn that the Knicks play somewhere on earth.

Maybe an analogy one can use is, if you say the genome is a recipe book - the recipe book doesn't do you any good till you decide which recipes to use. In the same manner, you have to express genes, and not all genes are expressed in all places.
A striking analogy exists between the splanchnic and the cardiac nerves. The cardiac nerves are three in number; they arise from all three cervical ganglia, and are distributed to a large and important organ in the thoracic cavity.
In a loose analogy to computing, one can think of a homeobox gene like a call to a subroutine. It switches on the production of a whole subsystem, the code for which must already be present elsewhere in the DNA.

The term proposed by Haldane (1941), by analogy with chemical isomerism, to describe a double heterozygote in coupling phase, that is, with the two dominant factors derived from one parent and the two recessives from the other.
Lipid alkoxyl radicals are presumed to be the species responsible for metal-amplified lipid peroxidation because of the chemical analogy of simple organic alkoxyl radicals to the hydroxyl radical.
In reality, the weasel program is significantly different from most genetic algorithms, and therefore Dembski's argument from analogy does not hold up.
Named by (humorous?) analogy with Southern blot which it greatly resembles.
An analogy (none are perfect) would be that the genes are like beads and chromosomes are like strings of beads. Since most eukaryotic organisms have tens of thousands of genes, they have many chromosomes.
An analogy can be made to child custody: the children are like electrons, and tend to spend some time with one parent and the rest of their time with the other parent.
Polyploid
Having three or more (Gk. polys, many) sets of homologous chromosomes. The term was introduced by Strasburger (1910) by analogy with his earlier terms haploid and diploid.
