the following cross was performed AaBbccDDEe X AaBBccDdEe WH

the following cross was performed AaBbccDDEe X AaBBccDdEe

WHat is the probability of obtaining a genotype of AABBccDdee or aaBBccDDEE

Solution

ANSWER:

AaBbccDDEe X AaBBccDdEe

LOCUS 1:Aa X Aa =1/4 (AA), 1/2 (Aa), 1/4 (aa)

LOCUS 2:Bb X BB =1/2 (BB),1/2(Bb)

LOCUS 3:cc X cc =ALL cc

LOCUS 4:DD X Dd = 1/2 (DD), 1/2 (dd)

LOCUS 5:Ee X Ee =1/4(EE), 1/2(Ee), 1/4(ee)

Probability of obtaining a genotype of

AABBccDdee: 1/4(AA)x1/2(BB)x1(cc)x1/2(Dd)x1/4(ee)

1/4x1/2x1x1/2x1/4=1/64

Probability of obtaining genotype is 1/64

or

aaBBccDDEE= 1/4(aa)x1/2(BB)x1(cc)x1/2DD)x1/4(EE)

1/4x1/2x1x1/2x1/4=1/64

Probability of obtaining genotype is 1/64..
