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

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.

The ancestors of plants that lived in water had plenty of water for the young. angiosperms are a group of land plants that evolved a reproductive trait for living on land. this trait protect young plants by allowing them to grow only when water is present and the conditions for healthy development are right. what trait most likely young angiosperms in this way?
