Why is it likely that MOST speciation is allopatric?

Biology
1 answer:
LenKa [72]3 years ago
6 0

Answer:

e. Because gene flow between populations prevents genetic divergence in sympatry.

Explanation:

Speciation requires genetic divergence between populations of a species to isolate them reproductively. however, when present in the same habitat, gene flow between populations of a species does not allow their reproductive isolation and thereby, prevents the formation of new species. These populations need strong episodes of disruptive selection for their reproductive isolation.  

On the other hand, two geographically isolated populations can not interbreed and thus, there is no gene flow between them leading to their genetic divergence and speciation. So, allopatric speciation is more common than sympatric one.

Which organelle contains both DNA and RNA?
muminat

Answer:

Nucleus

Explanation:

The nucleus is the organelle that contains the genetic material of eukaryotic organisms. That is, the DNA is contained in the nucleus while RNA is formed in the nucleus and transported out of the nucleus into the cytoplasm. This means the DNA and RNA can be present in the nuclues at the same time.

What does the term strain mean as it is used in genetic crosses
LUCKY_DIMON [66]

In biology, the strain is a low-level taxonomic rank used in different contexts:

In microbiology, a strain is a part of a bacterial species different from other bacteria of the same species by a minor but identifiable difference. Strains are often created in the laboratory by mutagenesis existing strains or wild-type examples of bacterial species.

In zoology, a strain corresponds to an individual or group of individuals who are at the origin of a line of descendants, sometimes called the holotype, paratypes, etc. A strain is a population of organisms that descends from a single organism or pure isolate culture. Strains of the same species may differ slightly from each other in many respects.

A strain thus consists of a group of organisms of the same species possessing certain differential traits based on their relationship; either they come from the same region, as the same watershed of a river, or they are the fruit of a particular breeding program (exists as a whole interbreeding without introductions from external sources).

Silicate minerals polymerize to form a variety of structures. three-dimensional structures have ________ silicon than those comp
Ksenya-84 [330]

The three-dimensional compositions have more silicon in comparison to those composed of independent tetrahedra.  

The silicate minerals refer to the most general of Earth's minerals and involve feldspar, quartz, mica, pyroxene, amphibole, and olivine. On the other hand, the silica tetrahedra composed of oxygen and silicon, produce sheets, chains, and frameworks, and bonds with other cations to produce silicate minerals.
