    Introduction In a paper published in the  March 22, 1984 edition of the Journal "Nature", researchers Clatton-Brock, Albon, and Guinness investigate the phenomena of maternal dominance, breeding success, and birth sex rations in polygenous red deer (Cervus  elaphus) populations on the Isle of Rhum in Scotland between 1971 and 1983. The intent of this investigation is to determine the importance of female dominance in regard to  the production of male offspring. The contention is presented that dominant mothers are responsible for the births of more male offspring than female offspring, a contention which suggests that  the breeding success of her male deer offspring is more determined by the social rank of the mother than is the breeding success of the female offspring.  Methods Clatton-Brock, Albon, and Guinness (1984) investigate the breeding success of  approximately 120 red deer hinds and 100 stags as it relates to the social dominance of the mother. The authors assigned values on social dominance based on the number  of other mature hinds (one year or older) the female had been observed to threaten or displace in normal herd activities (Clatton-Brock, Albon, and Guinness, 1984). This value was  then further refined by being weighted by the ranks of the other hinds (Clatton-Brock, Albon, and Guinness, 1984). The researchers also took into account observed incidences of the hind  not only threatening or displacing other hinds but also being displaced or threatened by these hinds (Clatton-Brock, Albon, and Guinness, 1984). The latter value, weighted by the social rank
