A
What is term for the capacity of an organism to stay alive?
viability
Name the term for the capacity of an individual to survive and pass on alleles to viable offspring
fitness
What is the term for the measure of fertility- thus the capacity to reproduce?
fecundity
What is the factor that influences the survival of an individual within a population called?
selection pressure
What type of selection tends to favour organisms with a phenotype similar to their parents and which usually occurs when the environment is very stable and unchanging and selects against extremes of phenotype?
stabilising selection
What type of selection favours one type of phenotype is, causing the allele frequency to shift in one direction?
directional selection
What type of selection operates in favour of extremes and against intermediate forms?
disruptive selection
What is the formula to calculate allele frequency?
Allele frequency = number of times the allele of interest is observed in a population / total number of all the alleles at that particular gene locus in the population
