Davenport in 1910<\/a>. Most textbooks present the specific hypothesis first proposed by Davenport \u00a0that two pairs of genes are involved which act\u00a0cumulatively and with intermediate effects in <a href=\"http:\/\/en.wikipedia.org\/wiki\/Zygosity#Heterozygous\" target=\"_blank\">heterozygotes<\/a>, so that negro pigmentation may be symbolized by <em>AABB<\/em>, white by <em>aabb<\/em> and various shades of diverse hybrid pigmentation by <em>AABb<\/em>, and <em>AaBB<\/em> (dark <a href=\"http:\/\/www.mixedracestudies.org\/?p=451\" target=\"_blank\">mulatto<\/a>) <em>AAbb<\/em>, <em>aaBB<\/em>, and <em>AaBb<\/em> (mulatto), and <em>aaBb<\/em> and <em>Aabb<\/em> (light mulatto). In a general way this hypothesis fits the data on negro-white hybrids collected by Davenport. Undoubtedly, however, it is at best only a first approximation. Pigmentation is greatly variable in either whites or negroes. While it is known that much of this variability is inherited, little information is available as to the specific genetic conditions underlying the degrees and types of pigmentation found in either group. Correspondingly limited is our knowledge of the interaction of the &#8220;minor&#8221; genes for pigment variability with each other and with the &#8220;major&#8221; ones in negro-white crosses.<\/p>\n<p>Read the entire article <a href=\"http:\/\/jhered.oxfordjournals.org\/content\/38\/8\/233.full.pdf\" target=\"_blank\">here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Skin Color of Children from White By Near-White Marriages The Journal of Heredity Volume 38, Number 8 (August 1947) pages 233-234 Curt Stern (1902-1981), Professor of Zoology and Genetics [Read a biographical memoir by James V.
