Question 5. 180 seconds. Q. In 1911, Thomas Morgan collected the following crossover gene frequencies while studying Drosophila. NettetWhen two genes remain in the same chromosome they tend to be inherited together to the offspring. This is called linkage and two genes are linked.

She crosses a fly homozygous for quiver and vestigial traits with a fly homozygous for the wild-type traits and then uses the resulting $\mathrm{F}_{1}$ females in a testcross. flugzeit washingtonNettetThere are different methods to detect linkages among genes. Some of these are: Detection of linkage by PD/NPD ratio The Parental generation (PD) to non-parental generation ratio gives indication about linkage between two genes. Test cross or back cross is performed in order to obtain PD/NPD ratio. greenery for place settings
