Analysis of the Pattern of Retroposition

Direction of the gene formation event		Expectation		Observed No.	Excess (%)
Direction of the gene formation event		%	No.	Observed No.	Excess (%)
X→A	23.3	5.6	12	114
A→X	20.3	4.9	3	−39
A→A	56.4	13.5	9	−33
	X² = 9.55, df = 2, P = 0.0084

[i] X, X chromosome; A, autosome; Excess = [O − E)/E] × 100;E, expected; O, observed.
