Fisher's principle is an evolutionary model that explains why the sex ratio of most species that produce offspring through sexual reproduction is approximately 1:1 between males and females. A. W. F. Edwards has remarked that it is "probably the most celebrated argument in evolutionary Biology".
What else can I help you with?
What is the smallest number of distinct points that can define a plane?
Three. That is why three-legged stools are always stable--the ends of their legs define a plane.
Organisms that employ a strategy of slow reproductive usually require an environment that whats?
Organisms that employ a strategy of slow reproduction usually require a stable environment with few changes and low mortality rates to ensure the survival of offspring. This allows for more parental care and investment in each offspring, leading to a higher chance of survival in their environment.
Define an example of an organism?
an assembly of molecules that function as a more or less stable whole and has the properties of life.
What is punctuated equilimbrium?
Punctuated equilibrium is a theory in evolutionary biology that suggests species will often remain stable for long periods of time (equilibrium), with evolutionary changes occurring rapidly (punctuation) in short bursts when they do happen. This concept contrasts with the traditional view of gradual and continuous evolutionary changes over time.
Is radius caused by stable or unstable nucleus of atoms?
all nuclei, both stable and unstable, have a radius. although the exact size can be hard to define, due to quantum properties.
Which scale in WAIS- III is the most stable measure of intelligence?
The vocabulary subtest: The ability to define words is not only one of the best single measures of intelligence but also the most stable.
Define the term marginal stability?
Marginal Stable is nothing but neutrally stable it means that the object will come back to original state even the external forces are acting on it but in different position.
How do you define a star in astronomy?
A star is any hydrostatically stable plasma that generates heat and electromagnetic radiation by nuclear fusion.
Define corrosion?
Corrosion is a natural process, which converts a refined metal to a more stable form, such as its oxide, hydroxide, or sulfide.
Which evolutionary factors are responsible for the periods of relative stasis?
The environment, of course. A stable environment and there is no selection pressure on the organism so stasis results. ( according to punctuated equilibrium )
Definition of retrenchment strategy?
A strategy used by corporations to reduce the diversity or the overall size of the operations of the company. This strategy is often used in order to cut expenses with the goal of becoming a more financial stable business. Typically the strategy involves withdrawing from certain markets or the discontinuation of selling certain products or service in order to make a beneficial turnaround.
According to the theory of punctuated equilibrium when does stasis occur?
Stasis in the theory of punctuated equilibrium refers to long periods of evolutionary stability without significant change in a species. This stasis occurs between shorter bursts of rapid evolutionary change or speciation events.
