19. Dax just completed a report on car transportation. He concluded that gasoline prices will likely rise significantly in the years to come and recommends lower-
cost car transportation for the future. Dax's younger sister, Ava, just completed a
report on air pollution. Ava concluded that gasoline-powered cars cause too
much pollution and recommends that they should not be used in the future.
Which of the following is a solution for the future that would follow both Dax's
and Ava's recommendations? *
O development of cars that run on fuels that pollute less and cost less than gasoline
enactment of laws that require gasoline to cost more and cause more pollution
O development of gasoline-powered cars that have better fuel efficiency
O enactment of laws requiring all people to ride bicycles instead of driving cars

This problem has been solved! see the answeryou are investigating two traits in fruit flies controlled by one gene each. the b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). after crossing rugose black flies with smooth brown flies, you obtain an f1 generation of 100% smooth black flies.what are the dominant alleles? (1 pt)what are the genotypes of the two parent flies to perform a dihybrid test cross? (1 pt)after running a dihybrid test cross, you find 1000 offspring with the following phenotypes: , rugose406black, smooth86brown, rugose94brown, smooth4141000fill in the expected column with the expected number of offspring in each class of phenotypes. (1 pt)what phenotype classes represent the recombinant offspring? (1 pt each)calculate the relative genetic distance between the body color gene and the body sculpting gene (show your work). (1 pt).
