Genetics how to find absolute and relative fitness
An organism’s absolute fitness is the total number of surviving offspring that an individual produces during its lifetime (its lifetime reproductive success).
some things that contribute to fitness are: its chance of living to a certain age (age specific survivorship), its number of offspring during a certain time interval (age specific fecundity).
These are called components of fitness.
Relative Fitness
For mathematical purposes, absolute fitness is standardized to get relative fitness.
Imagine there are several genotypes, each codes for a different phenotype. The genotype with the highest absolute fitness has a relative fitness of 1.0
For every other genotype, their relative fitness is: absolute fitness of that genotype/absolute fitness of fittest genotype
