At first I thought the OP posted those particular pairings based on what he owned. But his .sig says only one normal.

Anyway, it is important when trying to figure out genetics, to understand it does not matter with any one particular pairing, which is the male and which is the female. So with the first example given, pastel female x spider male, the results would be exactly the same for pastel male x spider female.

When choosing what to buy for your breeding project, it does make a big difference what is male & what is female. A male can breed several different females each year and therefore produce lots of clutches each year. But a female can only produce 1 clutch per year, and some people think that breeding them every year is too stressful and only breed the females on alternate years or maybe 2 out of 3 years.
