inbreeding
the mating of related individuals (more closely related than the average population)
1 of 7
Benefits of inbreeding
All have good traits - more likely to be passed onto offspring, offspring = more outstanding genetic merit
2 of 7
Downside
more unfavourable genes
3 of 7
effects of inbreeding in homozygosity and heterozygosity
Increases homozygous genotypes, and decreases heterozygous genotypes.
4 of 7
polygenic trait
controlled by two or more than two genes (usually by many different genes) at different loci on different chromosomes
5 of 7
Inbreeding depression
A reduction in fitness resulting from mating between close relatives that occurs by chance in small populations or by assortative mating in large populations - especially reproductive rate and disease resistance
6 of 7
inbreeding coefficient
The probability that both alleles at a single locus are identical by descent- copies of a single gene inherited from a common ancestor
