You can then assemble a pedigree for the known individuals. By using the map on page 48 and sightings data, you will track the origins and movements of particular lions and then will analyze their genotypes to ascertain how each is related to the others. Females have been known to move but often remain in the same pride for many years with their female relatives. Juvenile male lions often leave their pride as they approach maturity to look for other prides in which they can mate with females and produce cubs of their own. By using genetics to establish maternity and paternity, we can now find the truth! Procedure In Namibia, field researchers have followed several lion prides that have been established for quite some time. You will then attempt to determine the true mother and father of the cubs in question. In this story, you will travel to Namibia and track lions, including our heroine, Lulu, and hypothesize how they travel by using sightings data. It is, of course, difficult to determine true parentage for each cub due to the presence of so many possible males and females in a social group. Researchers have been studying lion prides to gain a better understanding of how their social hierarchy works and if alloparenting the caring for young by family members other than the parents is present in this species. When new males enter a pride, they displace the resident males and then may kill any existing cubs in order to mate with resident females and produce offspring of their own. Background In lion prides, there are often one or two males who join a pride in an area with several females and their cubs. The Life of Lulu the Lioness: A Heroine s Story Name: Objective Using genotypes from many individuals, determine maternity, paternity, and relatedness among a group of lions. ![]()
