When dealing with small inbreeding populations, such as the NARW population, it can be difficult to determine paternities because more than one male can share a particular genotype. Paternity analysis is important because it provides insights to male reproductive success. Male NARWs do not expend any energy taking care of their offspring; calves rely solely on mom to provide food and protection. Therefore, we cannot determine a calf’s father based on observations of behaviour, we need to create a genetic profile of the calf , determine which alleles he/she obtained from mom and then compare the leftover alleles to known male profiles. Paternity is only assigned when all but ONE male has been eliminated. Currently, we have 105 paternity results. Choose an individual by its ID number in the boxes provided or view the Father-Mother-Calf Triad table below for easy comparisons. More information on each whale can be found by clicking on the DIGITS link at the top of the page and searching the ID number.
