Alex73 [517]

Answer:

33.3 cM

Explanation:

Parent 1: blue shell, long antenna : BBLL

Parent 2: green shell, short antenna : bbll

BBLL X bbll :

F1 : BbLl ( blue shell, long antenna )

BbLl X bbll :

BL/bl = 82 : Parental

bl/bl = 78 : Parental

Bl/bl = 37 : Recombinant

bL/bl = 43 : Recombinant

Total = 240

Recombination frequency = (Number of recombinants/ Total offspring)*100

= (80/240) * 100 = 33.33 %

Map distance = recombination frequency

Hence, map distance = 33.3 cM
