In a cross of two pure-breeding lines of tomatoes producing different fruit sizes, the variance in grams(g) of fruit weight in the F1 is 2.10 g, and the variance among the F2 is 6.00 g.

Part A) Determine the genetic variance VG for the trait.( 3 sig figs)
Part B) Determine the environmental variance VE for the trait. (3 sig figs)
Part C)Determine the broad sense heritability of the trait.(3 sig figs)
