Amelogenesis imperfecta is an X-linked dominant condition that affects tooth enamel. Affected males have extremely thin enamel layers all over each tooth. Female carriers, however, have grooved teeth from the uneven deposition of enamel. Explain the difference in phenotype between the sexes for this condition.

females are not completely affected, they have an x chromosome that doesnt have that condition

If heterozygous females have uneven deposition, this means that females have teeth with thick enamel and thin enamel. Having both forms of the gene expressed at the same time is a case of codominance. Males would not be able to get this uneven condition because they only have one X-chromosome. Males would either have thin enamel or normal enamel. They can never be heterozygous.
