No statistically significant negative inbreeding effect could be shown. A high inbreeding coefficient per se does not make an individual unsuitable for breeding. This is better reflected in the mean kinship (mk) of an individual, where mean kinship is the average relatedness of an individual to all other individuals in the zoo population. In zoo population: Number of founders 33 Founder genomes surviving 21.806 Mean inbreeding coefficient 0.079 Mean kinship 0.0634 Gene diversity 0.9366 Founder genome equivalents 7.8893 End
sexual maturity females 5 years, earliest reproduction in captivity, female 4 years 128 days.
Sexual maturity: males 9 years, females 5 years Earliest reproduction in captivity: female 4 yrs 128 days, males 7 yrs 7 months. The reproductive phase lies between 4 and 32 years in females, between 7 and 40 years in males. The age-specific fertility shows a concave shape. In contrast, no age-specific decline of fertility in males can be detected in the date. Average generation time is 15 years.
