Genetics

Question 1

How much genetic information is shared between individuals?

Answer 1

~95%

Question 2

What are the types of genetic variation between individuals?

Answer 2

1. Single-nucleotide polymorphisms (SNPs)
2. Indels

Question 3

What are the effects of paternal age on de novo mutation rate in offspring?

Answer 3

Increased paternal age gives rise to more de novo mutations.

Question 4

What is genetic sweep?

Answer 4

When beneficial gene is inherited, genes nearby that undergo low rates of recombination ‘hitch-hike’ with beneficial gene.

Question 5

What is the use of genetic sweep in studying population genetics?

Answer 5

Reduction in genetic diversity around specific gene within population suggests that gene has been selected for.
