Paleness (pallor in Latin) is abnormal loss of color from normal skin or mucous membranes due to reduced amount of the blood in the skin arteries. Paleness should be distinguished from other causes of prominent white skin: Fair skin is genetically determined skin hue with low concentration of skin pigment (melanin) in the skin.
autosomal-dominant inheritance, a pattern of inheritance in which the transmission of a dominant allele on an autosome causes a trait to be expressed. Males and females are usually affected with equal frequency. pattern of inheritance in which the transmission of a dominant allele on an autosome causes a trait to be expressed.

But aa would make the a trait show up. As long as a pair of alleles has a dominant allele (A), the trait that the dominant allele represents would show up. Autosomal dominant is a trait that results when the allele combination is AA or Aa. Autosomal recessive is a trait that results when the combination is aa.For example, albinism is an autosomal recessive trait. That means if a person has two recessive alleles (aa), then that person WILL be an albino.ut aa would make the a trait show up. As long as a pair of alleles has a dominant allele (A), the trait that the dominant allele represents would show up. Autosomal dominant is a trait that results when the allele combination is AA or Aa. Autosomal recessive is a trait that results when the combination is aa.
