Final answer:

Dentin Dysplasia comes in two forms: Type I and Type II, with an autosomal dominant inheritance pattern. Deciduous teeth emerge around 6 months, permanent teeth around 6 years, and wisdom teeth generally during late teens or early twenties. The 'Law of Dominance' explains how a dominant trait can mask a recessive trait in a heterozygote.

Step-by-step explanation:

The two types of Dentin Dysplasia are referred to as Type I and Type II. This rare genetic disorder affects the development of dentin, the hard tissue that lies beneath the enamel of the teeth. The inheritance pattern of Dentin Dysplasia is autosomal dominant, meaning that only one copy of the altered gene is necessary for the affected individual to display the phenotype.

As for human teeth development, deciduous teeth, also known as baby teeth, typically emerge at about 6 months of age. Permanent teeth begin to replace deciduous teeth around 6 years of age. Wisdom teeth, or third molars, usually emerge in a person's late teenage years or early twenties, although they can appear much later or not at all.

The 'Law of Dominance' is a genetics principle, which was formulated by Gregor Mendel, stating that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. This hidden trait is called recessive, while the observable trait is described as dominant.

Regarding color blindness, there are several types, but if we were to refer to the three most commonly discussed types, they are: Deuteranomaly (green weak), Protanomaly (red weak), and Tritanomaly (blue weak). These conditions are caused by the alteration or absence of certain photoreceptor cells in the retina.
