Heredity, Ecology & Disease Flashcards
What is the Temporal Hypothesis?
Environments are unpredictable therefore sexual recombination should favour survival of families under these conditions (some recombinants will make it)
Where does phenotypic variability arise from?
P= G + E + GE
P= phenotypic variability G= genes E= environment
What is the Spatial Hypothesis?
Siblings may compete with one another because they tend to occupy the same environment, sexual reproduction will lead to new combination that will escape intraspecific competition
What is the Red Queen Hypothesis?
Sexual recombination may lead to a host to produce offspring that escapades infection from parasites. At the same time it would allow the parasite to track these changes in the host. (Example of frequency dependant selection)
