1) State Gause's Competitive Exclusion Principle.
2) Why is pedigree analysis done in the study of human genetics? State the conclusions that can be drawn from it.
1) According to Gause's Competitive Exclusion Principle, two species that fight for the same resources cannot coexist peacefully.
In the long run, one of the two competitors will always have a little advantage over the other, which will cause the second competitor to go extinct. As a result, competing related species frequently develop distinctive traits in environments where they coexist.
2) Pedigree analysis is the study of a family's history about the transmission of a specific trait over numerous generations. Because control crossings in people are impossible and because people are older, pedigree analysis is used in the study of human genetics. A specific trait defect or disease can be traced using pedigree analysis.
End of analysis. Great!
