Alchen [17]

Answer:

recombination frequency = 4.5% or 4.5mu

Explanation:

to calculate the frequency of recombination between these genes

we have,

recombination frequency = [ number of recombinnants/total number of offsprings) x 100

total offspring  = 88 + 103 + 6 + 3

total offspring =  200

Gl ra 88............................ parent

gl Ra 103.........................parent

Gl Ra 6..................................... recombinant

gl ra 3................................................ recombinant

recombination frequency = {6+3/88 + 103 + 6 + 3} x 100

recombination frequency = 9/200 x1oo

recombination frequency = 0.045 x 100

recombination frequency = 4.5% or 4.5mu
