Body Weight Increase

The mutation extra-toes (Gli3Xt-J) on chromosome (Chr) 13 of the mouse is known to be involved in the development of the skeleton. The only visible manifestation is the presence of an extra digit on each hind foot. Here we report evidence from several experiments that Gli3XtJ/+mice weigh more than littermate Gli3+/+mice, suggesting an effect on body weight ofGli3or of a gene tightly linked to it on Chr 13. Four independent experiments in different environments were conducted on mice with different genetic backgrounds derived from the C3XtEso Gli3Xt-J/+Eso/+linkage testing strain and the JE/Le strain at adult age. The analyses have shown an association between the Gli3Xt-Jallele and a body weight increase of about 6.5%. This effect is genetically dominant. It would appear that if the gene of interest is notGli3itself, it must be very close to this locus. Indeed, the expected size for this fragment is 7.9 ± 5.3 cM. The manifestation of this gene, observed in two animal facilities and on different genetic backgrounds, is consistent with the idea that the effect of the gene(s) is displayed in a stable manner. It accounts for a variation of 6.5% of body weight.

Product Number

When an account or product number is typed into a computer, there is often a quick way to check that the number had been entered correctly. One way is with a check digit, which is an extra digit at the end of the account number, representing the ones digit of the sum of the account digits, or some other formula.

AbstractA single right fifth metatarsal found in Tomb 1 at Peligroso, Belize exhibited a small deformity in the form of a small (7 mm) accessory digit emanating from the plantar surface at mid-shaft. This Type A postaxial polydactyly is the first archaeological example of polydactyly reported for Mesoamerica. Polydactyly is one of the more commonly reported morphological anomalies and thus its appearance in Maya populations would have been prevalent enough to demand explanation. A review of related terminology in pertinent Amerindian languages is presented as a means of exploring the manners in which digits and the human body are conceptualized. Maya iconographic representations of polydactyly at Palenque have parallels to other Mesoamerican renderings of supernumerary digits used to identify divinities and deified ancestors. However, the Peligroso mortuary context comprised disarticulated and commingled bones, suggesting that the individual did not have a distinctive social role related to the presence of an extra digit.
