  Some Hymenopteran queens mate with multiple males. Consider the case in which the queen mates with two different males: 1) Draw the genealogical diagram (like the ones in lecture) for half sib sisters. 2) Calculate the value of r for half sib sisters.
  NE P[rare allele came from father] NE 1. P[sister got same allele from father] Thus, for full sib sisters: P[share rare allele from mother) = 1/2 * 1/2 = 1/4 P[share rare allele from father] = 1/2 * 1 = 1/2 So: r = 3/4 For sisters relative to brothers: P[allele in sister also found in brother] = 1/2 * 1/2 = 1/4 P[allele in brother also found in sister] = 1 * 1/2 = 1/2 For mother/offspring, r = 1/2 For father/offspring, r = 1
