Question

Quizplus · Accepted Answer

When a heterozygous curly-haired person (Cc) and a person with straight hair (cc) have offspring, the possible genotypes of the offspring are Cc and cc. The C allele is dominant and results in curly hair, while the c allele is recessive and results in straight hair. Therefore, 50% of the offspring are expected to have straight hair (genotype cc) and 50% are expected to have curly hair (genotype Cc).
