The Difference

Differences between sexes in the duration of larval and nymphal quiescence in Ixodid ticks were investigated in Israel in the laboratory. In H. dromedarii Koch the larval quiescence of the male was, on average about 4 hours longer than that of the female, but in Rhipicephalus sanguineus (Latr.) no significant difference was found. In five species a statistically significant difference in the length of nymphal quiescence was found between males and females; in three of them, R. sanguineus, R. secundus Fel.-Muh. and H. dromedarii, that of the male exceeded that of the female by 1/2 to 1 1/2 days and in the other two, H. marginatum Koch and H. excavatum Koch, the opposite was found, the difference being 1·3 and 3·7 days, respectively.

SUMMARYTwo reciprocal mouse translocations T(2; 8)26H and T(1; 13)70H, heterozygous in a Swiss random-bred background, show differences in the spectrum of multivalent configurations and in the segregational behaviour of these multivalent configurations. T26H/+ males mostly contained rings of four (R IV, 53·15%) and T70H/+ males chains of four, missing a chiasma in the shortest interstitial segment (C IV 11, 61·55%). The adjacent II frequency, estimated from metaphase II observations, was 8·47% in T26H/+ and 25·22% in T70H/+. Univalents of the shorter translocation chromosome of T70H are able to divide equationally at first anaphase. The hypothesis is advanced that time differences in chiasma terminalization during metaphase I-anaphase are important for explaining the difference in segregation observed between the two translocations. Translocation-caused non-disjunction is probably low in T26H/+ and 4–5% in T70H/+. Univalents involving T70H/+ are usually capable of co-orientation with the other chromosomes of the translocation complex. The summed percentages of adjacent II disjunction and non-disjunction caused by the translocations were estimated from the relative fertility scores of T/+ males and females versus +/+ males and females as 9·8% and 29·0% for T26H/+ and T70H/+ males, respectively, and 9·4% and 27·8% for T26H/+ females and T70H/+ females. For both translocations, the agreement between the various estimates is good. Chiasma frequencies are much higher in telomeric segments than in proximal segments containing centric heterochromatin.

Every tribe and race has size of tooth mesiodistal and cervicoincisal different from each other. The most obviousdifference is the size of the teeth between female and male. This study aimed to determine differences in size ofmesiodistal and cervicoincisal maxillary central incisors between male and female of Buginese, Makassarese andTorajanese. The sample consisted of 30 Buginese, 30 Makassarese, and 30 Torajanese aged frem 18-25 years-old.After impression of the upper and lower jaw was taken, and size of mesiodistal and cervicoincisal tooth weremeasured. After the data were analyzed by t-test and ANOVA test, it appears that males have a larger size thanfemales. Makassarese has the longest mesiodistal size (8.41 mm), Buginese has the longest cervicoincisal size (9.83mm), whereas Torajanese has the smallest size of mesiodistal and cervicoincisal among the other tribes. It was concluded that the average sizes of mesiodistal and cervicoincisal of maxillary central incisors showed no significantdifference. While there are significant differences in the average size of the mesiodistal and cervicoincisal maxillarycentral incisors between the males and females, and based on tribe lines.

This study aims to compare EuroFit test results of 11-17-year-old males and females in Kosovo. 742 students were included in the study. 347 females and 395 males were determined by random selection from the schools in urban and rural areas of all regions. Kosovo's general population rate (52% male 48% female) was considered when determining the proportion of male and female students. Anthropometric characteristics including height, weight, and Body Mass Index (BMI) of students and the motoric characteristics including the values obtained from the tests such as flamingo balance, plate tapping, sit and reach, standing broad jump, handgrip strength, sit-ups (30 sec), bent arm hang, 10x5m shuttle run and 20 m endurance were compared. As a result, there was no statistically significant difference between the anthropometric characteristics of male and female students in adolescence; however, it was observed that as the age increased, males became heavier and taller than females (p<0.05). In general, while there was no statistically significant difference between males and females in flamingo balance, plate tapping and sit and reach tests (p> 0.05), males were determined to be more successful than females in standing broad jump test, handgrip strength test, sit-ups (30 sec) and 20 m endurance tests (p<0.05). It is observed that students in Kosovo are more successful than the other countries regarding motoric tests such as the anthropometric characteristics, which are thought to be more related to genetics, and speed/agility of arms and legs. On the other hand, they are unsuccessful in comparison with other countries with regard to flexibility and endurance in tests which are thought to be influenced by factors such as lifestyle, nutrition, and training.

This study aimed to examine inter-limb jump asymmetries and their association with sport-specific performance in young swimmers. Thirty-eight (male, n = 19; female, n = 19) regional/national level young swimmers (age: 12.3 ± 1.2 years; height: 159.6 ± 8.2 cm; body mass: 52.5 ± 9.2 kg) participated in this study. Inter-limb asymmetries were assessed for single-leg countermovement jump (SLCMJ) and single-leg standing long jump (SLSLJ). Sport-specific performance was evaluated using front crawl (i.e., 50 m and 25 m) and front crawl kick (i.e., 50 m and 25 m). The kappa coefficient revealed a “slight” level of agreement (Κ = 0.156, 0.184, and 0.197 for female, male, and all, respectively) between the direction of asymmetry for SLCMJ and SLSLJ, indicating that asymmetries rarely favored the same limb during both tests. A paired sample t-test showed a significant difference (p = 0.025) between asymmetry scores obtained in SLCMJ and SLSLJ. No significant difference was found in asymmetry scores between males and females (p = 0.099 to 0.977). Additionally, no association between asymmetry scores and sport-specific performance was observed (p > 0.05). Our findings highlight the independent nature of inter-limb asymmetries derived from SLCMJ and SLSLJ among young male and female swimmers. Further, our results suggest no association between jumping asymmetries and sport-specific performance.

The influence of social experience on the preferences for a potential mate in a captive population of black ducks, Anas rubripes, and mallards, Anas platyrhynchos, was examined. Birds were reared from hatching with conspecifics (i.e., female black ducks with male black ducks, female mallards with male mallards), or were cross-fostered with the other species (i.e., female black ducks with male mallards, female mallards with male black ducks). Preferences of individuals were tested in a chamber containing caged black ducks and mallards of the opposite sex. In over 90% (100/109) of the trials, males and females preferred the species that they were raised with since hatching, whether they were of the same species or not. These results demonstrate that social experience influences the social preferences of male and female black ducks and mallards.

AbstractDistribution pattern, prevalence and intensity of parasitaemia of heteroxenous apicomplexan blood parasite Hemolivia mauritanica and its vector tick Hyalomma aegyptium have been studied in 264 tortoises (212 Testudo graeca and 52 T. horsfieldii) throughout the Iranian territory. In T. graeca the highest prevalence and intensity of parasitaemia for H. mauritanica were recorded in the temperate mid and northern parts of the Iranian plateau, while the lowest values were found in the arid central part of Iran. No Hemolivia-positive samples were found in T. horsfieldii. Hyalomma aegyptium ticks were diagnosed in both tortoise species. The highest prevalence and intensity of infestation with H. aegyptium were recorded in western part of Iran, where climatic conditions are not so arid compared to central and eastern parts. No significant differences were found in intensity of parasitaemia of H. mauritanica between males and females. Similarly, no differences in intensity of parasitaemia were detected between different age groups (adults; more than 10 years, young; 5-10 years and juveniles; less that 5 years). Prevalence of H. mauritanica and H. aegyptium in adults was higher than in young and in juveniles. While intensity of infestation with H. aegyptium was significantly higher in adult tortoises compare to juveniles, no significant difference were found between intensity of H. aegyptium infestation in male and female tortoises.
