Question

1)Suppose we view all Spotted Owls on Earth as a single population. In this view, is gene flow possible?

A) No. When we say “Spotted Owls migrate”, this refers to the seasonal movement of individuals, not the transfer of individuals between populations. Only the second kind is “gene flow”. (Also, Spotted Owls don’t migrate.)

B)Yes. Gene flow is always possible, even if it doesn’t always happen.

C)No. If we view all Spotted Owls as a single population, there is no other population for individuals to come from or go to.

D)Yes. Spotted Owls are endangered, so gene flow is especially important to prevent inbreeding depression.

2)What is inbreeding depression?

A)the decrease in fitness that can occur when relatives mate

B)a form of mental illness found in geographically isolated populations :-(

C)the decrease in populations size that can occur when relatives mate

D)the decrease in heterozygote frequency that can occur when relatives mate

Answer 1

1--- gene flow occurs in 2 populations .. so 3rd answer gonna be right . Gene flow can occur in same species but there should be 2 populations.

2- inbreeding depression is the decrease in fitness that can occur when relatives mate and it increases homozygosity in generations.
