Do B chromosomes affect fecundity in yellow-necked mice Apodemus flavicollis (Rodentia, Mammalia)?
Abstract
The effects of the presence of B chromosomes on fecundity of the yellow-necked mouse Apodemus flavicollis were studied in 46 females without and 28 with Bs from four localities in Serbia. Uterine inspection showed that there was no significant difference in the mean number of scars and embryos between females with and those without Bs. Thus, B chromosomes do not appear to affect the fecundity of females carrying them, indicating that the presence of Bs does not affect fitness characteristics.
