Express your answer using three decimal places.

progeny that are expected to have a genotype identical to that of the parent.
Express your answer using three decimal places.

AaBbCcDdEe x AaBbCcDdEe

Aa X Aa = 1/4 AA
Bb X Bb = 1/4 BB
Cc X Cc = 1/2 Cc
Dd X Dd = 1/4 dd
Ee X Ee = 3/4 E_

1/4 X 1/4 X 1/2 X 1/4 X 3/4 = 3/512 = 0.00585= 0.585 %
