Chromosome maps/genetic maps were first prepared by

A has 3 maps and B has 9 maps.All the 12 maps being distinct.Determine the number of ways in which they can exchange their maps if each keeps his initial number of maps.

if A={1,2,3) to B={a,b,c,d} for f:A rarr B then find number of (i) mappings (ii) one-one mappings s (ii) many-one mappings (iv) onto mappings (v) into mappings (vi) constant mappings

If A={1,2,3,4} and B={a,b,c} for f:A->B find the total number of (i) mappings(ii) one- one mappings(iii)many-one mappings (iv) onto mappings (v) into mappings (vi) constant mappings

What map unit (Centimorgan) is adopted in the construction of genetic maps?
