You are studying the inheritance pattern of hair color in troll dolls, which have XY sex determination. You cross a true-breeding blue-haired male with a true-breeding orange- haired female. The F1 offspring (males and females) are all orange-haired. You cross an F1 orange-haired female to an F1 orange-haired male. What phenotypic ratio would you expect if the troll doll hair gene is X-linked? Fill in each blank with a numeral (ie, 0, 1, 2, 3, 4, etc). Do not include extra spaces or decimals. Use "0" if a phenotypic group would not be present. Make sure your ratio is reduced (ie, use,2:1 rather than 4:2). 1:1 1:1 orange-haired females : 1:1 orange-haired male : 1:1 blue-haired females : blue haired males

![You are studying the inheritance pattern of hair color in troll dolls, which have XY sex
determination. You cross a true-breeding blue-haired male with a true-breeding orange-
haired female. The F1 offspring (males and females) are all orange-haired. You cross an F1
orange-haired female to an F1 orange-haired male.
What phenotypic ratio would you expect if the troll doll hair gene is X-linked? Fill in each
blank with a numeral (ie, 0, 1, 2, 3, 4, etc). Do not include extra spaces or decimals. Use
"0" if a phenotypic group would not be present. Make sure your ratio is reduced (ie, use,2:1
