1.	In an experiment with drosophila eye colour purple/red and wing shape normal/vestigial you observe that offspring mainly have either purple vestigial trait or red normal trait. What is the expected parental trait?(a) Purple long and Red long(b) Red Vestigial and purple long(c) Red vestigial and purple vestigial(d) Purple vestigial and red vestigialThe question was posed to me during an interview for a job.The doubt is from Dihybrid Cross in portion Mendelian Genetics of Cytogenetics
Answer» The correct CHOICE is (d) Purple vestigial and red vestigial Explanation: In this CASE, drosophila SHOWS the linkage between these two GENS, so the parents must having the trait that is mostly PRESENT in the offspring.
