Inhaltsangabe

Excerpt from Elementary Genetics

Hereditary examples are drawn from a wide range Of living things, from phage to Pferde (horses). There is a comprehensive chapter on coat color inheritance in mammals. A chapter is devoted to the comparatively new field Of biochemical genetics, and another to biochemical genetics in man.

Some traditional illustrations of heredity will not be found in this book. For instance, I have not brought in the inheritance of blue versus brown eyes in human beings. There are so many genes modifying eye color that it is difficult, without a breeding test, to tell the true inheritance or genotype of an individual. Much unhappiness has been caused by a literal interpreta tion of the dictum that the gene for blue eyes is recessive and that blue-eyed parents can never have'a brown-eyed child. Eyes that are blue-gray may in fact be the manifestation of a heterozygote for blue and brown. Two such persons could very well have a brown-eyed child. Modifiers undoubtedly affect the major gene for eye color, and it is highly probable that there are cases of low expressivity of the gene for brown that has produced apparently blue eyes in the parent but could give rise to brown eyes in the ofispring. For this reason the inheritance of eye color in human beings will not be dealt with in the text. This is the last reference to it.
