You want to increase fruit diameter in tomatoes, and you want to estimate heritability for this trait. You measured the diameter of tomatoes in two inbred lines, the F1 hybrid between these two lines, and the F2 generation. The variance for tomato diameter in inbred line 1 was 4.1 cm?. The variance for tomato diameter in inbred line 2 was 3.6 cm2. The variance in the F; generation was 4.6 cm?. The variance in the F2 generation was 21.3 cm2. Calculate the values below. Type in only the numerical value and round all answers properly to 3 decimal digits. Phenotypic Variance = cm2 Environmental Variance = cm? Genetic Variance = cm2 Broad-sense Heritability = Which cross is considered to be a backcross? F2 x Inbred Line 2 F1 x F2 CF1 x F1 F2 x F2 F1 x Inbred Line 2 CInbred Line 1 x Inbred Line 2 If broad-sense heritability for a trait is very high and narrow-sense heritability is very low, which of the following must be true? Dominance variance must be high relative to phenotypic variance CAdditive variance must be high relative to phenotypic variance Environmental variance must be high relative to phenotypic variance You want to increase fruit diameter in tomatoes, and you want to estimate heritability for this trait.
