Inbreeding Flashcards
What is genetic drift?
The process of losing genetic variation by chance
Which population of elephant seals had less variation?
Northern
What is the monoculture effect?
Genetically homogenous host populations are more vulnerable to infection than genetically diverse populations
How much is heterozygosity lower in threatened species?
35%
What is Wright’s inbreeding coefficient (f)?
The standard measure of the degree of inbreeding of an individual
What is f if parents are full siblings?
0.25
What is f if parents are cousins?
0.0625
What is f?
The probability of inheriting two alleles that are identical by descent
What are small, isolated populations vulnerable to?
Loss of genetic variation from genetic drift
Inbreeding depression
Lowered evolutionary potential
Compromised reproductive fitness
Elevated extinction risk
What do Californian Condors suffer from?
Chondrodystrophic dwarfism
What does conservation genetics aim to do?
Reduce the loss of genetic variation and avoid inbreeding
