Mishnayos Yevamos Perek 2 Mishnah 5

In the case of anyone who has a brother of any kind, that brother creates a levirate bond causing his yevama to be required to perform levirate marriage if the first brother dies childless. And he is his brother in all respects, except for one who has a brother born from a Canaanite maidservant or from a gentile woman, as these do not have the legal status of brothers. Similarly, in the case of anyone who has a child of any kind, that child exempts his father’s wife from levirate marriage, since his father did not die childless. And that child is liable to receive capital punishment if he strikes his father or curses him. And he is his child in all respects, except for whoever has a child born from a Canaanite maidservant or from a gentile woman, as these do not have the halakhic status of children.

מִי שֶׁיֶּשׁ לוֹ אָח מִכָּל מָקוֹם, זוֹקֵק אֶת אֵשֶׁת אָחִיו לְיִבּוּם, וְאָחִיו לְכָל דָּבָר, חוּץ מִמִּי שֶׁיֶּשׁ לוֹ מִן הַשִּׁפְחָה וּמִן הַנָּכְרִית. מִי שֶׁיֶּשׁ לוֹ בֵּן מִכָּל מָקוֹם, פּוֹטֵר אֵשֶׁת אָבִיו מִן הַיִּבּוּם, וְחַיָּב עַל מַכָּתוֹ וְעַל קִלְלָתוֹ, וּבְנוֹ הוּא לְכָל דָּבָר, חוּץ מִמִּי שֶׁיֶּשׁ לוֹ מִן הַשִּׁפְחָה וּמִן הַנָּכְרִית:
