What is morphological divergence?
What is morphological divergence?
Morphological divergence is related to habitat types that differ climatically. Morphologically, the species boundary is clear between P. guinanensis and P. vlangalii but not between other two pairs of species.
What is genetic morphology?
Divisions of morphology Functional morphology is the study of the relationship between the structure and function of morphological features. Experimental morphology is the study of the effects of external factors upon the morphology of organisms under experimental conditions, such as the effect of genetic mutation.
Does gene flow increase genetic divergence?
Gene flow within a population can increase the genetic variation of the population, whereas gene flow between genetically distant populations can reduce the genetic difference between the populations.
What are examples of morphological convergence?
The evolutionary development of similar structures in two or more species, often widely separated phylogenetically, in response to similarities of environment; for example, the wings in insects, birds, and flying mammals.
What’s the difference between morphological divergence and morphological convergence?
A divergent pattern occurs when the characters of closely related species are more dissimilar in areas of sympatry than areas of allopatry, whereas in a convergent pattern, the characters are more similar in areas of sympatry than in areas of allopatry.
Is gene flow random or nonrandom?
Non-random gene flow versus random gene flow: gene flow is random for a given trait (e.g., morphology, physiology or behavior, type of current habitat, or genotype) if all dispersal characteristics of individuals (i.e., dispersal probability, distance, or destination) are uncorrelated with the genetic variation in this …
What is the difference between convergent and divergent evolution?
Whereas convergent evolution involves unrelated species that develop similar characteristics over time, divergent evolution involves species with a common ancestor that change to become increasingly different over time.
