It comprises two rounds of division, producing four cells with only one copy of each chromosome as a final product (haploid). Additionally, each chromosome undergoes genetic material cross-pollination between the paternal and maternal copies before division, resulting in novel combinations of the genetic code on each chromosome.

What adaptation is commonly found in organisms of deep pelagic and benthic communities?
Gigantism is the adaptation commonly found in organisms of deep pelagic and benthic communities.
What is adaptation?The biological process through which organisms adapt to new surroundings or modifications in their present settings is known as adaptation in evolutionary theory. Even while adaptation was a topic of discussion among scientists before the 1800s, Charles Darwin and Alfred Russel Wallace did not create the idea of natural selection until then.
Wallace thought that adaptation of organisms to shifting environmental conditions was somehow related to the evolution of species. Wallace and Darwin both went beyond basic adaptation when formulating the notion of evolution by natural selection by describing how organisms adapt and evolve.
According to the theory of natural selection, features that may be handed down enable animals to adapt to their environment more effectively than other members of their own species. As a result, the species evolves because it can survive and reproduce better than other members of the species.
Therefore, gigantism is an adaptation found in deep pelagic and benthic communities.
