3)a.Postzygotic barriers
A reproductive barrier that prevent hybrid zygotes produced by two different species from developing into viable, fertile adults.
4)d.Evolution
The founder effect occurs due to the loss of genetic variation in a new population is formed from a small number of individuals from a larger population.
5)a. jersey
my DOG NAME IS JERSEY
6)a.The contribution an individual makes to the gene pool of the next generation relative to the contribution of other individuals
This is relative fitness or Darwinian fitness
7)a.Time barrier, le Different mating seasons
Temporal isolation means 'isolated intime,' so this is a mechanism that prevents species from mating.
8)b. That all forms of life are related to some extent through branching evolution from earliest organism
