A national park needs to perform selective logging in their forested area. In order for logging trucks to access the area, roads will need to be installed across a previously undisturbed area of forest. The forest is home to many species of trees (hickories, oaks, and maples), multiple herbivores (deer, rabbits, squirrels), and higher level consumers as well (wolves, hawks).

What would be required in order to approve the road construction on federal lands in this national forest?

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
