The effect is approximately additive, where individuals with one copy of the allele have intermediate expression of shovel-shaped incisors and homozygotes have more strongly shoveled incisors. [10] The trait is pleiotropically related to thicker and straighter hair shafts, other dental traits, sweat glands, and mammary gland ductal branching.
Odontoblasts are large columnar cells, whose cell bodies are arranged along the interface between dentin and pulp, from the crown to cervix to the root apex in a mature tooth.
Teeth affected by regional odontodysplasia nevAmelogenesis imperfecta is an autosomal dominant disease characterized by a defect in dental enamel formation. Teeth are often free of enamel, small, misshapen, and tinted brown. The cause of these deformities is due to a mutation in enamel in expression.

This is seen, for example, throughout The Cambridge Dictionary of Human Biology and Evolution. The greatest number of teeth in any known placental land mammal [specify] was 48, with a formula of 3.1.5.3 3.1.5.3. [9] However, no living placental mammal has this number. In extant placental mammals, the maximum dental formula is 3.1.4.3 3.1.4.3 ...

The primordium contains each of the primordial tissue types, essential for the development of successive teeth. These primordial tissues together form the enamel organ, dental papilla and dental sac. Also during the cap stage is the formation of a depression within the deepest part of each tooth bud of the dental lamina. The dental lamina is a ...
