Rabbits produce large numbers of offspring
during each reproductive season, yet the
number of rabbits within a given population
changes very little from year to year. The
stability of the population size is most likely the
result of
(1) the development of mutations in young
rabbits
(2) environmental factors that keep the
population in check
(3) rabbits continuing to reproduce when the
population is large
(4) the survival of more female rabbits than
male rabbits
