To make that a little clearer, we can say it means having a similar relative position, structure, function or origin. So, literally, it means having the same relation. We will be continuing with this etymology as we discuss the various definitions of 'homologous' that are found in biology.The term homologous comes from the Greek 'homos' meaning same and 'logos' meaning relation. Noticing a pattern? Words with the prefix 'homo' all have the idea of sameness in their meaning.
A homosexual is a person sexually attracted to a member of the same sex. If a group is homogenous, all of its members are uniform or consistent.
For example, the flippers of a whale, the forelimbs of a frog and man have the same basic structures but they perform different functions, hence these are called homologous organs.EtymologyA homophone is a word that sounds the same as another but has a different meaning. They are different and have a different purpose, but they are similar and share common traits.Homologous organs may be defined as the organs of different animals which have similar basic structure but different functions. For example, the ovaries and testes both develop from the embryonic gonad.Following are some examples of homology: The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. In terms of sexual differentiation, organs are considered homologous if they develop from the same embryonic tissue. (2) biology : having the same or allelic genes with genetic loci usually arranged in the same order homologous chromosomes.Homologous Organs:Developmental biology refers to homologous organs in the males and females of a species. (1) biology : exhibiting biological homology. 1a : having the same relative position, value, or structure: such as.
