Is there any standard for the notation of a crossing (hybrid) which tells me which part is the mother and which is the father?

StrainA: egg cell
StrainB: sperm cell

Which notation is correct?
StrainA x StrainB or
StrainB x StrainA
or isn't there a rule for this?


For plants, seed (egg cell) parent is shown first and pollen (sperm) parent second.

The rule is mentioned in wikipedia, http://en.wikipedia.org/wiki/Hybrid_(biology)

section : in plants.

Another mention of plant example:
