dN/dt = rN (K-N/K ) The logistic equation above is used to describe the rate of change of a population, N, with time, t, Where r is the intrinsic rate of increase and K is the carrying capacity. What is value of per capita growth rate when population size is 200 individuals? ( K= 400, r =.25)

In balancing selection, two or more alleles are kept in balance, and therefore are maintained in a population over the course of many generations. Which of the following example can support balancing natural selection?

A- Sickle cell allele kept in balance because heterozygotes have greater chance of survival if infected by the malarial parasite, compared with normal homozygotes

B. One morph has selective advantage over another morph

C. One homozygote has greater chance of survival than other genotype results in purity of population

D. many species of invertebrates exist as different colored forms, identical in all respects except color. Visually searching predators often develop a search image for one color form, usually the commoner
