#Unit 8. Inheritance Biology

We can construct a genetic map by considering the recombination frequencies for each pair of genes. The recombination frequency between a and b is 50%, a and c is 50%, and b and c is 20%. What will be the correct prediction about this statements;

a)  Recombination frequency between genes a and b and gene a and c is expected with independent assortment

b) The genes a and b and gene a and c may either be on different chromosomes or be very far apart on the same chromosome;  so we will place them in different linkage groups

c) The gene b and c are linked

d) The gene b and c are unlinked
