Question

An example of stabilizing selection would be: All lizards have equal survival rates, regardless of size. Small lizards do not survive cold winters, while very large lizards are more visible to predatory birds and experience high rates of predation Hence intermediate sized lizards are more common. Larger lizards are too large for predatory birds, and hence are less vulnerable to predation. Small lizards are able to avoid detection while large lizards are too big to be preyed upon Hence the lizards of intermediate are commonly preyed upon. Two populations of the same species that have migration of individuals between populations are said to have __. Gene flow Genetic inheritance Genetic Drift Natural Selection

Answer 1

5. An example of a stabilizing selection would be small lizards do not survve cold winter, while very large lizards are more visible to predatory birdsand experience high rates of predation. Hence intermediate sized lizards are more common.

Stabilizing selection selects against individuals with extreme phenotypes, and favors the intermediate variants.

6. Two populations of the same species that have migration of individuals between populations are said to have gene flow or gene migration which is the the transfer of alleles or genes from one population to another.
