Hi there, i was wonder if the recombinat frequency determined by a
supplementary cross, or a test cross has the more accurate value and why.

In my testcross i found the rf to be 0.091, and in a supplementary cross,
the rf = 11.4

Supplementary cross:
Cross 1 P1:  Unknown  x yellow forked (marker)
Supplementary Cross 1:  F1 WT female   x  Oregon R males

P1A:	unknown  x  oregon males
TCA:	F1A female  X   unknown males

Thanks, Randy.
