Closely related species whose populations are sometimes allopatric showing greater morphology similarity but in a sympatric with distinct morphology due to

#Unit 10. Ecological Principles
  1. Sympatric populations, which would potentially intraspecific competition for resources, show differences in body structures and in the resources they use
  2. Sympatric populations may influenced to dissimilar environmental condition, differences in body structures and in the resources they use
  3. Sympatric populations, which would potentially compete for mate choice, show differences in body structures and in the resources they use
  4. Interspecific competition in this system could change the morphology of competing species of sympatric population

 With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 
You do each PCR reaction and load each one into a separate well of an agarose gel, and then run the gel.
