b130 dev1: Extremely subtle differences in next generations even though mutation is set to zero

When I set mutation to zero I would expect no mutations to occur. Yet there are very subtle differences between some new strategies and last generation strategies  implying either mutation is still occurring OR only a tiny part of one parent makes it in to the child. If breeding is occurring properly without mutation we should see more characteristics in child made of each parent than one single variable.

In the screenshots are one example of a previous generation strat vs present generation strat. The highlight is the only difference in the pseudocode. Mutation is still set to zero so no mutation should be happening. This is generation number 2.
