Question

There are some gene pairs in which neither allele is dominant, and when both alleles are present in the chromosomes both traits are expressed in the phenotype. The resulting heterozygote phenotype is in between the two different homozygote phenotypes. For example: RR (red petals) and rr (white petals) produce Rr or pink petals in offspring. This pattern of inheritance is called incomplete dominance.
In humans, straight hair can be represented as SS and curly hair as ss. Hair texture exhibits incomplete dominance. A man with curly hair (ss) has children with a woman with wavy hair (Ss). What are the chances that their children will have curly hair?
A) 100&
B) 50%
C) 25%
D) 0%
