Question Description
I’m working on a biology discussion question and need a sample draft to help me learn.
Fine-tuning of seasonal timing of breeding is regulated downstream in the underlying neuro-endocrine system in a small songbird

Answer the following questions as you progress through the assigned reading.
Question 1: What was the author’s hypothesis regarding the control of timing of breeding in birds?
Question 2: What types of birds did they use for this research? Give one advantage and one disadvantage of using the species and sample population used in this paper.
Question 3: What is a candidate gene? What is a reference gene?
Question 4: Which molecular technique did the authors use in this study: ELISA, CRISPR, FISH, PCR? What is one advantage of using this method to address the hypothesis, rather than another molecular technique?
Question 5: In which tissue(s) did the authors report the greatest differences between treatment groups? Does this suggest that timing of breeding is controlled by upstream (hypothalamus, pituitary) or downstream (ovary, liver) tissues in the HPGL axis, or both?
