Molecular Ecology Flashcards
1
Q
What are the main problems with breeding within a small population?
A
Inbreeding, homozygosity, loss of alleles and allele frequency.
2
Q
Why is inbreeding a problem?
A
Reduction in fitness: poor resistance to disease, loss of fecundity, progeny survivability, extinction.
3
Q
What is this reduction in fitness known as?
A
Inbreeding depression.
4
Q
What is homozygosity?
A
It is the reduction of the number of alleles as a consequence of inbreeding depression.
5
Q
A loss of genetic diversity is known as what?
A
Genetic bottleneck.
6
Q
What are molecular markers?
A
Sections of the genome, generally small, that are expected to represent larger sections of the genome.
7
Q
What molecular markers are tandemly repeated, e.g. ATATATAT ?
A
Minisatellites
