The following distribution of offspring was observed:
blue wings, green eyes 1,070
blue wings, black eyes 177
red wings, green eyes 180
red wings, black eyes 1,072
in a particular species of mammal, blue wings (b) are dominant to red wings (b), and green eyes (g) are dominant to black eyes (g). based on these data, what is the recombination frequency? (see book section: module 9.18)
a. 86%
b. 7
c. 17%
d. 14%

When should a bar graph be used? a. when there is no independent variable. b. when the independent variable is continuous and does not show a relationship to the dependent variable. c. when the independent variable is continuous and shows a causal link to the dependent variable. d. when the independent variable is composed of categories and does not show a relationship.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
