Question

Q1) This is one of three questions that require you to match the following naturally occurring polymorphisms with the phenotypes they influence:

Wing spots in Drosophila biarmipes males ___________.

single amino acid change in the beta-globin subunit of the hemoglobin protein

deletion within a regulatory sequence of the Pitx1 gene

Q2) This is one of three questions that require you to match the following naturally occurring polymorphisms with the phenotypes they influence:

Coat color variation in pocket mice of the US desert southwest ___________.

exon deletions in the OCA2 gene

gain-of-function allele of the MC1R gene associated with 4 amino acid substitutions

single amino acid change in the beta-globin subunit of the hemoglobin protein

deletion within a regulatory sequence of the Pitx1 gene

mutation in a regulatory sequence governing expression of the yellow gene

Q3) This is one of three questions that require you to match the following naturally occurring polymorphisms with the phenotypes they influence:

Albinism in blind cave fish in Mexico ___________.

single amino acid change in the beta-globin subunit of the hemoglobin protein

exon deletions in the OCA2 gene

Solutions:

1) Option 3- mutation in a regulatory sequence governing expression of the yellow gene

2) Option 2- gain-of-function allele of the MC1R gene associated with 4 amino acid substitutions

3) Option 3- exon deletions in the OCA2 gene
