Question

A research group has isolated ten fruit fly mutants (A to J) defective in sensing the light direction. These mutants were shown to be monogenic recessive. To determine how many loci/alleles these mutants represent, a complementation test was performed, as shown in the following table. Note that in the table "-" represents the light sensing defect mutant phenotype for F1 derived from various crosses, while "+" indicates the normal light direction sensing phenotype as observed in wild-type. Please draw a conclusion based on this complementation test result by designating a genotype for each of these mutants in the "Mutant genotype" column.

Explanation / Answer

According to the information, a complementation assay has been conducted for knowning the mutation status for the microbes for specific locations. This can be clearly understood from the tabulated data that atleast one allele location shows a negative phenotype with respect to a particular allele location. This negative result gives rise to a mutant phenotype in the microbe. Thus, the required genotypes of the microbes can be found as enlisted below (the monogenic recessive site has been indicated as -):
