During allopatric speciation

Biology
1 answer:
Kruka [31]3 years ago
7 0

Answer:

A. a geographic separation occurs between subpopulations

Explanation:

Allopatric speciation, which can also be called geographic speciation, is a type of speciation that involves the isolation of biological populations of the same species. This isolation is caused by geographical changes which include, formation of islands, mountains, and bodies of water. Social changes, brought about by human activities such as urbanization and agriculture, also aids Allopatric speciation.

The isolation of subpopulations from each other will lead to the gene flow being interfered or hindered.

Wewaii [24]

Answer:

look

Explanation:

Flatworms, roundworms, and segmented worms are all invertebrates. Some species of each type of worm are free-living, meaning they are not dependent on another organism.Some are parasitic.

Flatworms belong to phylum Platyhelminthes. They do not have a coelom, respiratory system or a circulatory system.Tapeworms flukes are examples of flatworms.

Roundworms are part of the phylum Nematoda. They are bilaterally symmetrical invertebrates.They have a psuedocoelom. Ascaris lumbricodes is the most common human parasite.

Segmented worms are the most complex animals of these three invertebrates. They are placed in Annelida. Segmented worms have a true coelom, a circulatory system and a digestive system.An earthworm is a segmented worm.

which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?
KATRIN_1 [288]

An example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation is option B: replacement of a polar amino acid with another polar amino acid at the protein's surface.

A frequent and well-known example of a missense mutation is the blood condition sickle-cell anemia. Missense mutations exist in the DNA at a single location in sickle-cell anemia patients. A different amino acid is required in this missense mutation, which also alters the overall structure of the protein. Similarly, replacement of a polar amino acid by another polar Ami no acid at the protein's surface is a missense mutation causing change in a single site.

A neutral mutation is one whose fixation is unrelated to natural selection. Therefore, the independence of a mutation's fixation from natural selection can be used to define the selective neutrality of a mutation.

Complete question is:

Which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?

a) Replacement of a polar amino acid with a nonpolar amino acid at the protein's outer surface

b) Replacement of a polar amino acid with another polar amino acid at the protein's surface

c) Replacement of a polar amino acid with another polar amino acid in the protein's interior

d) Replacement of a polar amino acid with a nonpolar amino acid in the protein's interior
