Question

two species if lizard (we will call them a and b) share a hybrid zone that is 6000 km in length and only 20 km wide. the frequency of the alleles specific to species a decrease from 100% at one edge of the hybrid zone down to 0% on the other end, while the alleles specific to species b decreased from 100% on the other side of the hybrid zone to 0% on the opposite edge. these allele frequencies are depicted on the graph below. predict how this gene distribution will change over time if fusion occurs. explain your answer.

Answer 15

Genetic diffusion is basically genetic mixing. You have two very distinct genetic gradients in this model. It tells you that your lizards are two different species - and by definition, members of different species cannot breed with each other. But the individuals of each species can definitely migrate, and over time you'd expect them to migrate. So you'd expect the genes to become evenly distributed over the geographic region, all other factors equal.

Answer 16

thanks mane

Answer 17

so even doe they dont mate the genes become distributed

Answer 18

Given the info you have, the genes become evenly distributed. Some 'type a' lizards move into 'type b' lizard territory - and vice versa. So given enough time, the distribution will become the same.

That said, there must be a very clear biologic reason why those two lizard species developed that distribution. As in lizard A is plainly better suited to conditions at one end of the territory, and lizard B is plainly better suited to conditions at the other end of the territory. So in real life, unless whatever factors led to the establishment of the uneven distribution in the first place changed, less genetic diffusion would occur. In my opinion.

Answer 19

okay i got thanks for elaborating that for me @blues

Answer 20

not a prob. :)
