Question

this passage describes the bekko patterning trait in koi fish: the bekko pattern is a pattern of colors found on the bodies of some koi fish. a koi fish with bekko patterning has black patches all over its body. a koi fish without bekko patterning does not have these patches. in a group of koi fish, some individuals have bekko patterning and others do not. in this group, the gene for the bekko patterning trait has two alleles. the allele b is for having bekko patterning, and the allele b is for not having bekko patterning. bubbles, a koi fish from this group, has bekko patterning. bubbles has one allele for having bekko patterning and one allele for not having bekko patterning. based on this information, click the blue words to correct any errors in the text. bubbles is heterozygous for the bekko patterning gene. bubbless phenotype for the bekko patterning gene is bb. bubbles has bekko patterning. this is bubbless genotype for the bekko patterning trait.

Explanation:

To solve this, we analyze each statement:

1. First Statement: "Bubbles is heterozygous for the Bekko patterning gene."

Heterozygous means having two different alleles (one dominant, one recessive). Bubbles has one \( B \) (for Bekko) and one \( b \) (not Bekko), so this statement is correct (no error here).

2. Second Statement: "Bubbles’s phenotype for the Bekko patterning gene is \( BB \)."

• Phenotype is the observable trait (e.g., having Bekko patterning).
• Genotype is the genetic makeup (allele combination). Bubbles has one \( B \) and one \( b \), so genotype is \( Bb \), not \( BB \). Also, \( BB \) is a genotype, not a phenotype.
• Correction: Replace "phenotype" with "genotype" and "BB" with "Bb" (or just note the error in the phenotype/genotype and allele combination).

3. Third Statement: "Bubbles has Bekko patterning. This is Bubbles’s genotype for the Bekko patterning trait."

• "Has Bekko patterning" is the phenotype (observable trait).
• Genotype is the allele combination (e.g., \( Bb \)).
• Correction: Replace "genotype" with "phenotype".

Final Corrections:

• Second sentence: Change "phenotype" to "genotype" and "BB" to "Bb" (or at least identify the error in phenotype/genotype and allele).
• Third sentence: Change "genotype" to "phenotype".

(Note: The first statement is correct. The key errors are mixing up phenotype/genotype and incorrect allele combination in the second statement, and mislabeling phenotype as genotype in the third.)

For the specific blue - word corrections:

• In "Bubbles’s phenotype for the Bekko patterning gene is BB":
• "phenotype" should be "genotype" (because \( BB \) is a genetic makeup) and "BB" should be "Bb" (since Bubbles has one \( B \) and one \( b \)).
• In "This is Bubbles’s genotype for the Bekko patterning trait":
• "genotype" should be "phenotype" (because "has Bekko patterning" is an observable trait).
