Scenаriо: As а mоleculаr biоlogist, you are investigating the genetic basis of olfactory behavior in Drosophila melanogaster. You are particularly interested in a gene referred to as Olf1, which has been previously linked to attraction to strawberry scent. In this scenario, Olf1 is defined as a dominant gene: Dominant allele (Olf1): Results in strong attraction to strawberry scent (Phenotype A). Recessive allele (olf1): Results in weak attraction to strawberry scent (Phenotype B). Expression: Olf1 is expressed in the olfactory sensory neurons in the fly brain. Questions:In a controlled experiment, you will use the Gal4-UAS system to knockdown Olf1 in the olfactory sensory neurons of Drosophila. 1. Explain how the Gal4-UAS system can be used to knockdown Olf1 specifically in the olfactory sensory neurons of Drosophila melanogaster (5 points). Describe the components of the Gal4-UAS system and how you would implement it to drive expression of a reporter gene. 2. Design a Mendelian inheritance study focusing on the olfactory behavior affected by the manipulated gene (10 points). The two parental strains to be crossed are: one strain with a homozygous dominant genotype (Olf1/Olf1) showing strong attraction to banana scent, and another strain that is homozygous recessive (olf1/olf1) with weak attraction. Describe the expected F1 and F2 generations' phenotypes and genotypes in relation to olfactory attraction to banana scent. 3. A colleague brings you another Drosophila mutant (known as Mutant B) that also exhibited reduced attraction to strawberry scent. Describe how you would design a complementation test between your initial mutant (olf1/olf1) and Mutant B to determine if they are allelic (mutations of the same genes) or non-allelic (mutations on different genes). Include the expected outcomes of the test and what they would indicate about the relationship between the two mutants (5 points).
