Question

Curly hair (C) is dominant where straight hair (c) is recessive. If a person who is Cc has children with a person that is cc, what is the probability of their children will have curly hair?

a
0%
b
25%
c
50%
d
75%

Answer 1

Answer: c. 50%

Step-by-step explanation:

If you draw a punnett square you see that the phenotypes you get are Cc, Cc, cc, and cc. If C (curly hair) is dominant over c (straight hair) then those with the phenotype Cc would have curly hair and those with the phenotype cc would have straight hair. 2 out of 4 have Cc (curly hair) so that's 50%.
