• Punnett Square

• Pedigree

• Phenotype

The dominant allele C represents curly hair, and the recessive allele is c. One of the parent's genotypes is dominant heterozygous Cc. Half of the offspring from the cross had straight hair and the other half had curly hair. Identify what the genotype of the second parent must be for 50% of the offspring to have straight hair.
