Allopatric speciation

Explanation:

Speciation is the gradual process by which two different species are formed from a single species due to evolution.

Allopatric speciation will occur when the speciation is due to geographical isolation of a species to the extend it prevents or interferes with the gene flow. Therefore, the populations can not mate with each other and they evolve separately.

This is what happened to the fox species when they were separated by a mountain range.

What is the correct sentence?
lorasvet [3.4K]

Answer: The correct sequence in the expression of a trait is gene > protein > trait (Option B).

Explanation:

During gene transcription, a linear fragment of DNA referred to as a 'gene' is used as template to synthesize a complementary messenger RNA (mRNA) sequence.

Subsequently, this mRNA is then used as template to create a protein by a process called translation.

Moreover, phenotypic traits can be defined as all observable characteristics that an organism has.

The phenotypic traits are largely determined by the expression of either enzymatic or structural proteins, which interact to shape the phenotype of an organism.

In conclusion, the correct sequence in the expression of a trait is gene > protein > trait (Option B).
