Probably J because it's higher in the lettering so it's also probably higher in high note ness, because I play the piano, I know this, the more frequency the more the pitch and the higher the pitch which is higher in the keyboard is higher in pitch.
The answer is both in males and females; only in males. Males
have one Y chromosome and one X chromosome, while females
have two X chromosomes. In mammals, the Y chromosome controls a
gene which is the SRY, which produces embryonic improvement as a male. The Y chromosomes of males and
other mammals also contain other genes needed for normal sperm production.
