Which of the following is the most predictable outcome of increased gene flow between two populations?
decreases genetic difference between two populations
What is gene flow?
Gene flow is genes moving between two populations. the transfer of genes from one gene pool to another two populations transferring genes
Two populations that have no gene flow between them are likely to?
If there is no gene flow between two populations then they will eventually become genetically distinct, thus forming two separate subspecies. If this isolation continues for longer still, then the 2 populations become so distinct that if you cross-bred between them, then no viable offspring could be produced. This would mean that they had become two separate species.
Why is isolation important in evolution?
It is the reproductive isolation between populations that allows divergence between populations, and ultimately speciation, to occur. Often this reproductive isolation is the result of geographical isolation, for instance when part of a population migrates to new territories.
Why does geographic isolation cause speciation (Apex)?
it prevents gene flow between populations
What is associative research design?
Associative research design is a type of research methodology that aims to establish relationships between variables by studying the statistical associations between them. It does not imply causation, but rather shows the degree of relationship between variables. This design is commonly used in fields such as psychology, sociology, and medicine to investigate correlations and patterns.
Are there negative correlations between two variables?
There can be. It depends on the variables.
What type of research studies population and is often used to search for correlation between dietary habits and disease incidence?
Epidemiological Study.
What has the author Wilson J Gaidry written?
Wilson J. Gaidry has written: 'Correlations between inshore spring white shrimp population densities and offshore overwintering populations' -- subject(s): Crustacea, Penaeus setiferus, Shrimps
Definition of ex post facto research?
Ex post facto research is a type of research design that investigates relationships between variables after they have occurred. In this design, the researcher does not have control over the independent variables, as they are pre-existing. The study is observational and looks for correlations or causality between variables that have already taken place in the past.
Does the relationship between the angle of incidence and the angle of reflection change as the angle of incidence increases?
no
Can ANOVA be used to test proposed relationships or predicted correlations between variables in a single?
To it cannot.
What is the difference between legal incidence and effective incidence?
The legal incidence is on the person or company who is legally obliged to pay the tax. Effective incidence refers to who actually ends up paying the tax.
The angle of incidence is the angle between the incident ray and the?
The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.
What is the difference between wild populations and natural populations?
nothing
What are angle of reflection and angle of incidence?
The angle of incidence is the angle between the incident ray of radiation (usually light) and the normal (perpendicular) at the point of incidence. Similarly, the angle of reflection is the angle between the reflected ray and the normal.
What is the incidence rate of parathyroidectomy performed?
Incidence rates vary between 25 and 50 per 100,000 persons.
