2.Fitness Flashcards
What does fitness indicate?
An individual’s ability to be successful at surviving and reproducing
What is fitness a measure of?
The tendency of some organisms to produce more surviving offspring that competing members of the same species
What does fitness refer to?
The contribution made to the gene pool of the next generation by individual gentoypes.
What is the equation for absolute fitness?
Frequency of a particular genotype after selection / frequency of a particular genotype before selection.
What does it mean if the absolute fitness is 1?
They frequency of the genotype is stable.
What does it mean if the absolute fitness is >1?
Conveys an increase in the genotype
What does it mean if the absolute fitness is <1?
Conveys a decrease in the genotype.
What is relative fitness?
It is the ratio of the number of surviving offspring per individual of a particular genotype compared with other genotype to the member of surviving offspring per individual of the most successful genotype.
