Which of the following statements about the evolution of life histories is correct?
A) Unstable environments with unlimited resources favor r-selected populations.
B) K-selected populations are most often found in environments where density-independent factors are important regulators of population size.
C) Most populations have both r- and K-selected characteristics that vary under different environmental conditions.
D) The reproductive efforts of r-selected populations are directed at producing just a few offspring with good competitive abilities.

If an individual is heterozygous for this translocation, the consequence in meiosis will be as follows:
A) Segregation results in a + c in one Gametes and b + d in another gametes, have duplication and deficiency so unable to produce viable offspring
B) Segregation results in a + b in one Gametes and c + d in another gametes, have normal chromosome so all viable offspring produced
C) Segregation results in a + d in one Gametes with normal chromosome and b + c in another gametes contains translocation arrangement, all viable offspring produced
D) Segregation results in a + d in one Gametes with normal chromosome, will produced viable offspring while b + c in another gametes contains translocation arrangement, will produce non viable offspring.
