Small populations
In small population sizes, inbreeding, or mating between individuals with similar genetic makeup, is more likely to occur, thus perpetuating more common alleles to the point of fixation, thus decreasing genetic diversity.
Answer:
What exactly is CER, and how does it work?
CER all starts with a question asked by the teacher. This question is based on a phenomena or lab experience. The student’s explanation or answer, as you may have guessed, will consist of three parts: a claim, the evidence, and the student’s reasoning.
Claim
A claim is a statement that answers the question. It will usually only be one sentence in length. The claim does not include any explanation, reasoning, or evidence so it should not include any transition words such as “because.”
Evidence
The evidence is the data used to support the claim. It can be either quantitative or qualitive depending on the question and/or lab. The evidence could even be a data table the student creates. Students should only use data within their evidence that directly supports the claim.
Reasoning
The reasoning is the explanation of “why and how” the evidence supports the claim. It should include an explanation of the underlying science concept that produced the evidence or data.
