#order-crossover

Order crossover (OX1) for permutation chromosomes copies a segment of parent $P_0$ into the child at the same positions. It then fills the open positions from left to right with the missing genes, in the order in which they appear in parent $P_1$.

$P_0$ = A B C D E F G H, $P_1$ = G D H B A F E C, and the copied segment is positions 3–5 of $P_0$. What is the child? Write its 8 letters in order.
