Formler

Question 1

Formlen for rekombinans

Answer 1

Rekombinante/totale afkom*100

Question 2

Chi i anden

Answer 2

X^2 = (obs-forv)^2 / forv

Question 3

Kromosomal interferens

Answer 3

I = 1-C. C=Obs. DO%/Forv. DO%

i = 1-C
C=(% obs DO)/(% forv DO)

%forv DO = afstand(a-b) afstand(b-c)100

Question 4

HWs to formler

Answer 4

1=p+q
1=p^2+2pq+q^2

Question 5

Parringstypefrekvens

Answer 5

AAAA=p^4
AaAA=22pqp^2
AaAa=2pq2pq
Aaaa=2p^22pq
aaaa=q^4

Question 6

Indavlskoefficienten og slægtskabskoefficienten

Answer 6

F=½*a
a=½^n.
a=½^n+½^n+½^n alt efter hvor mange fælles aner

Question 7

Singles formel for phat og Z^2

Answer 7

phat = A-A1/T-A1
Z^2 = (phat-P0)^2/Est.var

Question 8

Selektions/mutations ligevægtsfrekvens for recessiv og dominant

Answer 8

recessiv: q=Kvadratrod(u/s)
Dominant: p=u/s

Question 9

Mutationsrate og selektionskoefficient

Answer 9

u og s

Question 10
