You are working with a 160 million bp human chromosome. What are the minimum number of markers/loci you need to map genes to this chromosome?

At least 1, 2, 3, 4, 6, or 8? I think it\'s at least 8 markers/loci, am I correct? Thank you!

Solution

Minimum number of markers/ loci to map genes on a chromosome is 3. The crossing over can occur between 1 and 2 or 2 and 3 to map the smallest fragment, in any chromosome.
