Sponges show modular growth. Two populations with the same density may not show the same pattern of dispersion. Numbers in the two populations will increase at the same rate. Both populations will go to extinction. A strawberry plant produces many daughter plants, three of which become independent of the mother plant.
All plants are different ramets.
All daughter plants are different genets. Only plants attached to the mother plant are ramets. Plants which are independent are different genets. In many natural populations, most individuals die before reaching reproductive age. In natural populations randomly spaced individuals are rare.
