Question

in a group of fruit flies, some individuals have red eyes and others have brown eyes. in this group, the gene for the eye color trait has two alleles. the allele e is for red eyes, and the allele e is for brown eyes. a certain fruit fly from this group has brown eyes. this fly has two alleles for brown eyes. based on this information, click the blue words to correct any errors in the text. this fruit fly is homozygous for the eye color gene. this fruit fly’s genotype for the eye color trait is brown eyes. this fruit fly’s genotype for the eye color gene is ee.

Explanation:

1. For the first sentence: The term "homozygous" is correct here because the fly has two identical alleles (both for brown eyes), so no correction is needed for "homozygous".
2. For the second sentence: The genotype refers to the alleles (like \(ee\)), while "brown eyes" is a phenotype (physical trait). So we need to correct "brown eyes" to the appropriate genotype. Since the fly has two alleles for brown eyes (and allele \(e\) is for brown eyes), the genotype should be \(ee\).
3. For the third sentence: The fly has two alleles for brown eyes (allele \(e\) is for brown eyes), so having two \(e\) alleles means the genotype is \(ee\), which is correct, so no correction is needed for "ee".

Answer:

• First sentence: "homozygous" is correct, no change.
• Second sentence: Replace "brown eyes" with \(ee\).
• Third sentence: "ee" is correct, no change.
