Genetics Flashcards
1
Q
How much genetic information is shared between individuals?
A
~95%
2
Q
What are the types of genetic variation between individuals?
A
- Single-nucleotide polymorphisms (SNPs)
- Indels
3
Q
What are the effects of paternal age on de novo mutation rate in offspring?
A
Increased paternal age gives rise to more de novo mutations.
4
Q
What is genetic sweep?
A
When beneficial gene is inherited, genes nearby that undergo low rates of recombination ‘hitch-hike’ with beneficial gene.
5
Q
What is the use of genetic sweep in studying population genetics?
A
Reduction in genetic diversity around specific gene within population suggests that gene has been selected for.
