thank you travis and dice that defenitely helps with my unerstadnding i plan to try a few crosses this year but will need to isolate them and bag them as i have a heavy bee population.. i actually wasnt sure if a pl and rl can cross pollinate... i also wanted to check ifthe pl gene is a recessive gene and after several generations do recessive genes have he ability to remain stable

I just found this in a nearby thread. It's a great, concise, well constructed explanation:

F5 = 93.625% of gene pairs homozygous
F6 = over 96% of gene pairs homozygous
F7 = over 98% of gene pairs homozygous

The above is true if you are following lines selected from individual plants with each generation.

Whether or not you perceive your line as "stabilized" depends on the traits that you are looking at, and when they become homozygous. If you only looking at RL vs PL you can become "stabilized" at the F2 generation.

The number of generations required to become stabilized depends on how many traits are important to you, and also how many genes are involved in determining those traits.

After 7 generations a line is, on average, pretty well stabilized, but still segregates for a small number of traits, which may or may not be easily detected.
