They are examples of homologous structures. Although their forelimbs are used differently, the basic skeletal structure is the same and they are derived from the same embryonic origin. This holds true as well to the lower limbs of animals when the basic bone components include femur, tibia, and...
Therefore, it shows a close evolutionary relationship between the two organisms. How is "homologous" defined in biology? In biology, homologous means having the same position and structure, but different function. The prefix homo means "same" and the Latin root of the word means "agreeing"....
homologous1 having a related or similar position, structure, etc.; corresponding; exhibiting homology. 2 (in chemistry) describing compounds that form a series with successive constant differences in composition. 3 (in biology) of common ancestry; especially of organs and tissues that have a similar...

In biology, it is used, for instance, to pertain to bodily parts or structures indicating a common evolutionary origin, as in “homologous structures”. Ingenetics, it is used to pertain to a pair of chromosomes that have a similar structure. Referred to ashomologous chromosomes, they are chr...
The structure, however, is very different. The bat wing is made of bones, while the butterfly wing is made of something much thinner. Homologous structures tell us about the relationship between animals, showing that they develop from the same kind of animals. However, analogous structures are...
They are large (several microns) and have a complex internal structure that is connected with the cytosol and consists of interconnected knots and concave bridges with sizes in the range of 100nm. We called this structure trabecular meshwork. The luminal part of the megapinosome can be ...
1.Corresponding or similar in position, value, structure, or function. 2.Derived from the same species:a homologous graft. 3.BiologySimilar in structure and evolutionary origin, though not necessarily in function, as the flippers of a seal and the hands of a human. ...
The meaning of HOMOLOGOUS is having the same relative position, value, or structure. How to use homologous in a sentence. Did you know?
Genome integrity is critical for cell survival and function, and DNA double-strand breaks (DSBs) pose one of the most serious threats to genome structure [10]. Both endogenous factors, such as replication errors, and exogenous factors, such as ionizing radiation and chemicals, can cause DSBs. ...
