Most sex-linked, recessive traits including hemophilia and color blindness, appear more commonly in males. This phenomenon is best explained by which statement?
O Most of the genes on the X and Y chromosomes of males are recessive.
O Males have an X chromosome with dominant genes.
O Males only have 1 X chromosome and the Y chromosome is lacking the gene so they only need
1 recessive allele
In males, the recessive sex-linked genes appear only on the Y chromosome

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.
