You make it tough to answer this question because you are giving conflicting information. If curly hair were truly dominate you would have only 2 phenotypes (curly or straight) not 3 and you would have three genotypes (CC, Cc, cc) then you ask for genotypic % :both (you should have three) 25%CC 50%Cc 25%cc Genotypic ratio 1:2:1. Phenotypic % would be 2 not (3). You would have 75% curly and 25% straight. Ratio 1 CC : 2Cc ; 1 cc.
Now if you really have three phenotypes it may be that you have incomplete or co-dominance. CC : curly Cc wavy (in between) and cc straight. In this case your genotypic and phenotypic percentage would be the same 25% CC : 50% Cc :25% cc. With a ratio of 1 curly :2 wavy :1 straight.
I hope this helps you and not confuse you too much but your question is confusing. Also you might have better luck asking your question in biology rather than botany. Good luck.

Genotypes: CC, Cc, and cc
Ratio: 1 CC: 2 Cc: 1 cc
Phenotypes: There are only two possible: Curly and Strait
Ratio: 3 Curly: 1 Straight

CC = curly = 1/4 of offspring
Cc = curly = 1/2 of offspring
cc = not curly =1/4 of offspring
