Suppose a population of 8 wolves has produced 20 young in a year. if 7 wolves have died, how many wolves are in the population now? (assume no wolves have moved into or out of the population for other reasons.)

Aspecies of butterfly has alleles for wing color that are either blue or orange. when a blue butterfly and an orange butterfly mate, their offspring have wings that are both blue and orange. explain the process through which wing color is expressed.
