College of Cat Genetics: Student Seminar 3
by Patricia Turner
Effects of Multiple Gene Inheritance
A number of students have expressed puzzlement over the inheritance of colours which are not produced by the action of one single gene.
[Ed. Note: this article looks at the effects of multiple genes in different colors. I have made them into separate sections for easier reading.]This seminar will have explained that not all colours can be predicted without prior knowledge of the effect of one gene or genes upon others. Furthermore, there are variations in the color produced by genes known as polygenes--genes with small individual effect. Polygenes can be manipulated only by selection.Lilac/Lavender

Thus, an understanding of Mendelian genetics is only the beginning of any study in cat genetics and must be accompanied by an understanding of interaction effects, polygenic inheritance and many other factors.Address Correction
