dass Defining Species art C Gene flow and the biological species concept Recall that the biological species conoept defines a species as a group of whose members have the in nature and produce viable, fertle ofspring This means that al members of these populations (called conspecifics) can contribute to a common gene pool. Conspecifics are organisms or populations that belong to the same species. Genes are transferred between oonspecific populations through both direct and indrect fow. Biologists studying disease susceptibility in mice used genetic techniques to look for gene fow in 12 wild populations of mioe. The populations (designated Athrough L) were located along a 210km ransect The found evidenoe of gene flow between some, but not al, pairs of populations In the grid below, a*** indcates a pair of populations in which dieetgene flow was deteeted and a wandoares a that showed no evidence of direct gene fiow. For help reading this grid, see Hint 2.

Solution

Look at the population A: \"+\" at K whic means Direct gene flow.

Now look at K: Straight down you get \"+\" for both D and F which means direct gene flow. Also, H and I has \"+\" signs for D which shows indirect gene flow.

Look at population B: \"+\" at L which means direct gene flow.

Now look at L, straight down you get \"+\" for both E which shows indirect gene flow.

Look at population C: \"+\" at G and J which means direct gene flow.

So, in a nutshell :

Population A: K,D,H,I,F

Population B: L,E

Population C: G, J
