Hilaire, both in varieties and in species, that when any part or organ is repeated many times in the structure of the same individual (as the vertebrae in snakes, and the stamens in polyandrous flowers) the number is variable; whereas the number of the same part or organ, when it occurs in lesser numbers, is constant.
There are some cases where the family has only one son, thus the question of being polyandrous is not an issue.
Sperm economy is predicted by sperm competition theory when females can be polyandrous, mechanisms of last-male sperm precedence can be effective, and the probability that one male fertilizes a female's lifetime production of eggs is small (e.
Note that the presence of outer staminodes in a polyandrous androecium has often been interpreted as evidence for a reductive trend (see Ronse Decraene & Smets, 1992, 1993).
Tilghman and her colleagues recently stumbled upon a publication from the 1960s that described cross-breeding between a monogamous mouse species and a closely related polyandrous one.
For example, Gomendio and Roldan (1991) found that polyandrous species of both rodents and primates have longer sperm than their monandrous counterparts (see also Dixson 1993).
