TABLE I.

Prior probability P(z). Fifteen possible states of z are given in 10 categories. The prior probabilities for 15 possible states, z are presented in 10 categories. The prior probability for each state is constructed using the Laws of Mendelian Inheritance. p denotes the CNV-allele frequency in the population. Note that we define z = (copy number − 2). The three states that we will discuss primarily are marked in bold.

z		P(z)
Parents	Offspring
(0 0)	0	(1–p)4
(1 0) or (0 1)*	0	p(1–p)3
	1	p(1–p)3
(1 1)	0	p2(1–p)2
	1	2p2(1–p)2
	2	p2(1–p)2
(2 0) or (0 2)*	1	p2(1–p)2
(2 1) or (1 2)*	1	p3(1–p)
	2	p3(1–p)
(2 2)	2	p4

^*Each probability, P(z), represents only one of the two parents-offspring configurations.
