where is the sticky post on genetics ?
I ran across it once. Now that I have sprouted seed and have a mix of pl and rl plants I am curious as to what traits are dominant. The seed came from a cutting from a 2014 volunteer. In 2015 the cutting grew out as a salad sized red. The volunteer was beefsteak sized.

hi 4 season.
There's a sticky with links at the top of the page in the Crosstalk forum. RL is dominant over PL, so in a cross of RL X PL, the first generation or F1 will all be RL. In the second generation or F2, the expected ratio is 1/4 PL and 3/4 RL. Two of the three RL still carry the PL gene, but it's not expressed because of RL dominance. |

Volunteer in 2014 gave beefsteaks and and in 2015 same seeds from original volunteer gave you salad sized fruit. So as I see it, seeds you saved in 2014 from that cutting,I have no idea how many fruits you used for seeds,which can be important, but some seeds were the result of cross pollination,so no way to predict what will happen or what is dominant or recessive,IMO.

The volunteer was some sort of hybrid or seed from one, the 2015 plant was a cutting from the 2014 plant kept alive over winter. It was the cutting or clone of the first plant that had the smaller sized tomato. I refuse to believe (or don't want to)my soil is so much different across the garden to cause the size change. I saved seeds from the 2015 plant. Just counted 11 pl 21 rl.
