What do you mean by homologous?

Definition of homologous

1a : having the same relative position, value, or structure: such as. (1) biology : exhibiting biological homology. (2) biology : having the same or allelic genes with genetic loci usually arranged in the same order homologous chromosomes.

What is homologous in biology?

homology, in biology, similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor.

What is homologous and example?

Homologous structures may have different functions. For example, a human arm and a bat’s wing are considered homologous structures because they have the same bone structure, even though they obviously have different functions. In biology, the presence of similarities like this is known as homology.

What are homologous in chemistry?

A homologous series is a group of chemicals which have similar chemical properties and can be represented by a general formula. Chemistry.

What is homologous theory?

Definition of homologous theory

: a theory in botany: the sporophyte and gametophyte in plants are essentially alike, the sporophyte having developed by direct modification of the gametophyte — compare antithetic theory.

What is called heterogeneous?

Definition of heterogeneous

: consisting of dissimilar or diverse ingredients or constituents : mixed an ethnically heterogeneous population. Other Words from heterogeneous Synonyms & Antonyms More Example Sentences Learn More About heterogeneous.

What is homologous point?

The extremities of parallel radii of two circles are called homologous with respect to the similitude center collinear with them.

What is homologous series Class 10?

> A homologous series is a series of hydrocarbons which have similar chemical properties and they share the same general formula. They are organic compounds having similar structure and functional groups.

What does homologous mean in meiosis?

Homologous recombination is a type of genetic recombination that occurs during meiosis (the formation of egg and sperm cells). Paired chromosomes from the male and female parent align so that similar DNA sequences from the paired chromosomes cross over each other.

What does homologous mean in math?

homology, in mathematics, a basic notion of algebraic topology. Intuitively, two curves in a plane or other two-dimensional surface are homologous if together they bound a region—thereby distinguishing between an inside and an outside.

What are homologous organs 12?

An organ is known as a homologous organ if they have the same ancestor but the function differs. An organ is known as an analogous organ if they have the same structure but the ancestor differs. These organs have very similar structure and they perform nearly the same function.

What is homology and analogy?

Structures with similar anatomy, morphology, embryology and genetics but dissimilar functions are known as homologous structures. Structures that are superficially similar but anatomical dissimilar doing the same function are known as analogous structures.

What is isomerism and isomers?

Isomerism is the phenomenon in which more than one compounds have the same chemical formula but different chemical structures. Chemical compounds that have identical chemical formulae but differ in properties and the arrangement of atoms in the molecule are called isomers.

What is Humalog series?

A homologous series is a series of compounds with the same general formula, usually varying by a single parameter such as the length of a carbon chain. Compounds within a homologous series typically have a fixed set of functional groups that gives them similar chemical and physical properties.

What is alkynes homologous series?

Answer: homologous series is a series of compounds with the same functional group and similar chemical properties in which the members of the series can be branched or unbranched. The alkynes comprise a series of carbon‐ and hydrogen‐based compounds that contain at least one triple bond.

What causes homology?

Homology is resemblance caused by a continuity of information. In biology it is a unified developmental phenomenon. Homologies among and within individuals intergrade in several ways, so historical homology cannot be separated sharply from repetitive homology.

Why do we study homology?

Homology looks at the similarities that exists in living organisms in order to determine common ancestry. The similarities can be in the genes, physical appearance or function of structures. The gene is so homologous that it can be interchanged between species and still cause development of an eye.

What is antithetic theory?

Definition of antithetic theory

: a theory in botany: the sporophyte and gametophyte are basically distinct with the gametophyte representing the primitive ancestral phase and the sporophyte being a new structure resulting from increasingly retarded zygotic reduction — compare homologous theory.
