A description is given of a female infant with multiple malformations and mental retardation who died at 31 months. Cytogenetic studies indicate trisomy of the complete short arm of chromosome 5, resulting from the unbalanced segregation of a balanced translocation in the mother whose karyotype was interpreted as 46,XX,t(5; 15)(p11; p12). The karyotype of the proband was designated 46,XX, der(5...

Conversely, suppose all the low-order Fourier coe cients are 0. Since D̂(100 0) = Pr[x1 = 0] Pr[x1 = 1] = 0, x1 is equally likely to be 0 or 1, and similarly for the other xi's. Now let pa1a2 = Pr[x1x2 = a1a2]. Since x1, x2, and x1 x2 are all unbiased, we get the equations p00 + p01 = p00 + p10 = p00 + p11 = 1=2. Furthermore, p00 + p01 + p10 + p11 = 1. From these equations, we deduce that all of...
