2. Figure 1 An example of cellular memory.
The calico cat displays features of epigenetic inheritance. Her orange and black patches result from random inactivation of one or the other X chromosome, a mechanism for equalizing the dosage of X-chromosome genes between females and males. The white background is a consequence of a separate autosomal mutation that prevents pigment cell migration in the hair. (Photo: Nzrst1jx, Wikimedia Commons.)
