7. Which of the following is the formula for narrow sense heritability?a) R= h2/Sb) h2=Va/Vpc) H2=Vg/Vpd) QTL=v/T8. The tree with a genotype of AABBCC (100cm) is crossed with another tree with a genotype of aabbcc (40 cm). Assuming that three genes contribute equally and environment does not participate in determining height of this tree, what is the height of heterozygote AaBbCc ?a) 50b) 60c) 70d) 80 9. What proportion of the F2 offspring will grow to 70 cm in question #8?a) 1/16b) 20/64c) 20/128d) 10/64e) 1/810. If broad-sense heritability for a trait is very high and narrow-sense heritability is very low, which of the following must be true?a) Additive variance must be high relative to total phenotypic variance. b) Dominance variance must be high relative to total phenotypic variance. c) Environmental variance must be high relative to total phenotypic variance. d) Genotypic-environmental covariance must be high relative to total phenotypic variance
