Q

What is disruptive selection?

A

Min peak where max peak

17
Q

What is stabilising selection?

A

Peak is pinched in

18
Q

How is more likely to be carries of sickle cell anaemia?

A

Heterozygous individuals (carries)

19
Q

Balanced polymorphism?

A

p=t/(s+t)

20
Q

How is mutation selection balanced reached equiblium?

A

elimination of deleterious alleles is = to new mutations

21
Q

Does mutation increase or decrease heterozygosity?

A

Increase

22
Q

Does drift increase or decrease heterozygosity?

A

Decrease

23
Q

What is a non-synonymous mutation?

A

Changes amino acid

24
Q

What is a synonymous mutation?

A

does not change an amino acid

25
Q

Chromosomes are mosaics, what does this mean?

A

they depend on recombination, mutation, population and slection rates and time

26
Q

In large population, new mutations are more likely to be neutral to the population, why is this?

A

More genetic variability in the population

27
Q

What test for you use for neutrality?

A

Tajam’s D

28
Q

Why are neutrality test important?

A

to make assumptions about the demography populations

29
Q

How to determine species?

A

Cytogenetics

30
Q

How does cytogenetics work?

A

Polytene chromosomes

31
Q

How is nuclear DNA inherited?

A

Population size = 4Ne

32
Q

How is Mitochondrial DNA inherited?

A

single lineage, Ne
