Table 1. Number of PKH26-positive gonadal germ cells recovered from 7-day-old chick embryonic gonads observed in the gonads of recipient embryos (n = 40, means ± SE).

		Recipient
		Female # (n=23)		Male # (n=17)
		Left	Right	Left	Right
Donor
	Female # (n=26)	43.8 ± 9.4 a	32.5 ± 13.8 b	45.9 ± 10.6 a	28.3 ± 4.0 b
	Male # (n=14)	48.9 ± 10.8 a	39.0 ± 16.8 b	51.2 ± 8.2 a	34.8 ± 6.7 b

The number of fluorescence-positive GGCs observed in recipient embryos was not significantly different among the four possible sex combinations of exogenous GGCs and recipient embryos (P > 0.05). ^{a, b} The numbers of fluorescence-positive GGCs with different letters are significantly different between the left and right gonads of the recipient embryos at P < 0.05.
