The evidence is that, from the diagram we can see that only 2 chickens (3&5) actually have the allele showing that it is recessive as to actually have the condition both parents must have it. However, from the tree starting from chicken 3 and 4, no child actually has the trait as only 1 parent has the gene, so to have it both parents must have the gene.

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.
