Question

to r osos i 07020B101%20303 10. What is the relationship between the recombination frequency for inked genes and the spatial distance between these 2 genes? trated visually and proved that physical crossovers between homologous chromosomes occur using a strain of corn in which chromosome 9 had some unusual physical cbaracteristics? 12. Who constructed the first genetic map based of the fruit fly X chromosome based upon genetic crosses in 1931? Who were they a student of? 13. In a 3 point test cross: How do you determine the order of loci for a 3 point test cross? How do you determine which progeny represent non-recombinant, single crossover recombinant, or double crossover recombinant progeny? How do you determine where the crossover occurs in single crossover recombinant progeny? How do you calculate the distance between each pair of loci? How do you calculate the coefficient of coincidence and interference?

Explanation / Answer

10 The relationship between the recombination frequency and distance between two genes is that the percentage recombination frequency is equal to the spatial distance between those two genes in centimorgan units.

So, if the recombination frequency is 0.12 then percentage recombination frequency is 12% and spatial distance is 12 centimorgan or cM between those two genes.
