Answer the following question.
Explain linkage and recombination as put forth by T.H. Morgan based on his observations with the Drosophila melanogaster crossing experiment.
When a white eye Drosophila male (Xr Y) is crossed to a red eye female (XR XR), in the F2 generation all the females are red eyed and 50% males are white eyed. In a criss-cross test, when males are white eyed. In a criss-cross test, when a white eyed female (Xr Xr) is crossed to a red eye male (XRY), the F1 generation offspring had white eyed males while the female offspring bad red eyes. Instead of crossing of a white eyed female (Xr Xr} to a red eyed male (XRY), white eye female (XrXr) to white eye male (XrY) is crossed, the F1 generation will have the following phenotypes and genotype.
What was Morgan's observation when he hybridized yellow bodied white eyed female Drosophila to brown bodied red eyed male Drosophila and inter-crossed their progeny?
The genetic map distance between two genes located on the same chromosome can be analyzed by calculating ____________.
All the linked genes in a particular chromosome, constitute a ____________.
In a given plant, red colour (R) of fruit is dominant over white fruit (r); and tallness (T) is dominant over dwarfness (t). If a plant with genotype RRTt is crossed with a plant of genotype rrtt, what will be the percentage of tall plants with red fruits in the next generation?
Which of the following is a test cross?
When ‘Aa’ is crossed with ‘aa’, (A is dominant over a)
The enzyme involved in the process of crossing over is ______.
