In horses, the coat color black is dominant (b)over chestnut (b).the trotting gait is dominant (t)over the pacing gait (t). if homozygous black pacer is mated to a homozygous chestnut, heterozygous trotter, what will be the genorype and phenotype of f¹ generation?

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.
