Question

joel is practicing punnett squares. based on this sample, which box did he not fill out correctly? a. ee b. ee c. ee d. ee

Explanation:

Step1: Recall Punnett - square rules

In a Punnett - square for a single - gene cross with alleles E and e, we combine the alleles from the parents. The top of the square represents the alleles from one parent and the side represents the alleles from the other parent.

Step2: Analyze each box

• Box a: When the allele from the top (E) and the allele from the side (E) combine, the genotype is EE, which is correct.
• Box b: When the allele from the top (E) and the allele from the side (e) combine, the genotype is Ee, which is correct.
• Box c: When the allele from the top (e) and the allele from the side (E) combine, the genotype should be Ee, not ee.
• Box d: When the allele from the top (e) and the allele from the side (e) combine, the genotype is ee, which is correct.

Answer:

C. c
