You cross a true breeding tomato plant with large fruits to a true breeding plant that has small fruits. all of the f1 offspring have medium sized fruits, with a variance in fruit size of 0.06 cm2 . when you create f2 plants, the variance in fruit size is 0.60 cm2 . what is the broad sense heritability (h2 ) of fruit size?

Based on the observation that only male crickets produce a song, you hypothesize that a male's song is a form of communication to potential mates. you set up a simple experiment to test this hypothesis. in the laboratory, you place a male snowy tree cricket in enclosure a, which is adjacent to enclosureb. in enclosure b, you place other insects, one at a time, and observe their responses to the male's song. the enclosures are designed so that the two insects being tested cannot see or smell each other, but sound is transmitted from enclosure a to enclosureb.
