Which of the following are homologous

Flippers of whales and wings of birds considered as homologous organs because they both have the same anatomy, i.e., they have same skeletal structures, and they perform different functions. Flippers of whales are used to swim whereas the wings of birds are used for flight.

Which of the following organs are homologous?

So, the correct answer is 'Wings of birds and pectoral fins of fish'

What are homologous give 2 examples?

Methane , ethane ( C 2 H 6 ) , propane ( C 3 H 8 ) and butane ( C 4 H 10 ) belong to the homologous series of alkanes.
The general formula of this homologous series of an alkanes is.

What is homologous answer?

Homologous structure- are basic body structures of animals having similar structure but different function. Eg:- Arm of Human, wing of bat, and front leg of horse all of them have similar basic structures but entirely different functions. Yes, It is necessary that homologous structures always have a common ancestor.

What are 3 examples of homologous?

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. They are different and have a different purpose, but they are similar and share common traits.

What are 4 examples of homologous structures?

A dolphin's flipper, a bird's wing, a cat's leg, and a human arm are considered homologous structures.

Is an example of homologous organs?

An example of homologous organs is our arm and a dog's foreleg, our teeth and an elephant's tusks, potato, and runners of grass.

What pairs are homologous organs?

The organs which have the same fundamental structure but different functions are called homologous organs. Pectoral fin of rohu and forelimb of horse have the same fundamental structure, but their functions are different. Pectoral fin is used for swimming by rohu and forelimb is used for walking by horse.

What is homologous form?

What are Homologous Chromosomes? Homologous Chromosomes are made of chromosomal pairs of the same length and centromere positions for the genes corresponding to the same loci. Typically one of the chromosomes is inherited from the father and the other from the mother.

What are 2 homologous?

Definition. Two chromosomes in a pair – normally one inherited from the mother and one from the father. For example, the two copies of Chromosome 1 in a cell would be referred to as homologous chromosomes.

What are the types of homologous?

Dependent on the level of comparison four types of homology are defined: ( 1) Iterative ( = serial = homonomy), (2) ontogenetic, (3) di- or polymor- phic, and (4) supraspecific homology. The significance of all four types for evolutionary biology and phylogenetic analysis is outlined.

What is homologous series give Example 10?

Solution : A homologous series is a series of carbon compounds that have different numbers of carbon atoms but contain the same functional group. <br> For example, methane, ethane, propane, butane, etc. are all part of the alkane homologous series. The general formula of this series is `C_(n)H_(2n)+2`.

Why is it called homologous?

The word homology, coined in about 1656, is derived from the Greek ὁμόλογος homologos from ὁμός homos "same" and λόγος logos "relation". Similar biological structures or sequences in different taxa are homologous if they are derived from a common ancestor.

What is not an example of homologous organs?

So, the correct option is 'Wings of bat and birds'

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 an example of homologous characters?

We use homologous characters — characters in different organisms that are similar because they were inherited from a common ancestor that also had that character. An example of homologous characters is the four limbs of tetrapods. Birds, bats, mice, and crocodiles all have four limbs.

What is homology and example?

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. Examples of this include the front limbs of birds, bats, humans and lizards since they have the same structure.

Which are examples of homologous structures quizlet?

Examples of homologous structures are the bones of a cat's leg, bird's wing, whale's flipper and a human arm. They are homologous because they formed from the same embryonic tissue but developed into different mature structures.

Which of the following are best examples of homologous structures?

The correct answer is (B) Bat wing and human hand. Homologous structures are similar structures that arise through divergent evolution from a common evolutionary ancestor.
