You probably expect about 111 \"1\"s, 111 \"2\"s, 111 \"3\"s, 111 \"4\"s, 111 \"5\"s, and 111 \"6\"s. But not exactly 111 of each; you expect some deviation from that number. The male has only one X chromosome, so he can only pass on the yellow and white traits, and he is also yellow bodied and white eyed.
