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

Which of the following is the correct sequence?

In certain motile prokaryotes, dozens of different proteins comprise the motor that powers the prokaryotic flagellum. The motor has a complicated structure, and its various proteins interact to carry out its function. Based on Darwinʹs explanation for the existence of human eyes, how would he probably have explained the existence of such motors?
