Meiosis results in genetic variation among its product cells. One source of this genetic variation is the random distribution of maternal and paternal chromosomes, and the other source of genetic variation isa. crossing over occurring at prophaseb. the arrival of chromosomes at the spindle poles in telophase Ic. chromosomes condensing at prophase IId. the reforming of the nuclear envelope at interkinesis

Cell specialization occurs by the process ofa. reproductionb. differentiationc. maturationd. growth

Explain the difference between incomplete dominance and codominance

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.
