Question
A person homozygous recessive may have straight hair; a homozygous dominant curly hair, and a heterozygote wavy hair. What is the interaction between these alleles?*1 pointdominant / recessiveadditiveco-dominantincompletely dominant
Solution
The interaction between these alleles is "incompletely dominant". This is because neither allele is completely dominant over the other, and the heterozygote shows a phenotype that is intermediate between the two homozygous phenotypes (wavy hair, which is between straight and curly).
