Abstract
Mate choice is the very important part of sexual selection.
It is known that free mate choice is to provide the most viable
offspring are born. Researches on different animal species found
that viability from introduction to sexual maturity is significantly
higher in individuals born in crossbreeding in accordance with free
behavioral mate choice, compared to that in crossbreeding against
the mate choice. Making the choice, the female may rely on visual,
vocal or olfactory signals of male. Most of experiments evaluating
sexual choice allowing interactions with the animal, making it impossible
to determine the specific contribution of each separate signal.
Odor play a crucial role in intraspecific communication in rodents.
Individuals are able to recognize sex, reproductive status, genotype,
and diet and health condition conspecifics by odor. However, very
few articles unite olfactory signals from the male to information
about his paternal effects. In our research, we mated a male with
two females. The number of live embryos, their weight and the weight
of fetal placentas evaluated reproductive success of males. Naive
females in olfactory tests then evaluated the volatile urine fraction
of the males. Male urine samples were also analyzed using chromatography-mass
spectrometry analysis. In result, the naive BALB/c females prefer
males with low number of fetus in the litter compared to males with
high number of fetus in the litter. Instrumental method of analysis
approved the opportunity to differentiate between the groups of
males. Other pregnancy parameters did not affect naive females’
preference for male urine samples.
