Question

metamerism is shown by animal

Answer 1

In biology, metamerism is the phenomenon of having a linear series of body segmentsfundamentally similar in structure, though not all such structures are entirely alike in any single life form because some of them perform special functions.[1] In animals, metameric segments are referred to as somites or metameres. In plants, they are referred to as metamers or, more concretely, phytomers.

In animals

In animals, metamery is defined as a mesodermal event resulting in serial repetition of unit subdivisions of ectodermand mesoderm products.[1] Endoderm is not involved in metamery. Segmentation is not the same concept as metamerism. Segmentation can be confined only to ectodermally derived tissue, e.g., in the Cestoda tapeworms. Metamerism is far more important biologically since it results in metameres, also called somites, that play a critical role in advanced locomotion.

Metamerism can be divided into two main categories:

Answer 2

In biology, metamerism is the phenomenon of having a linear series of body segments fundamentally similar in structure, though not all such structures are entirely alike in any single life form because some of them perform special functions. In animals, metameric segments are referred to as somites or metameres.
