A-Level Biology Question Analysis Topic: Biology - Short Questions
Exam Questions:
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.
Answers:
For A-Level Biology, you should know:
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.
