Question 3

You have discovered an altered phenotype and cloned the gene responsible.However,the gene you cloned appears to have an unusual sequence in it.In order to determine the chromosomal location of your new gene,you perform FISH,using only the unusual sequence,on several animals.To your surprise,the FISH results suggest that each animal contains the gene on a different chromosome.How would you interpret your results?

Accepted Answer

The unusual sequence is a tran
