Beak color: y for yellow beak (yy and yy) and y for black beak (yy)< br />
tail-feather length: l for long tail (ll and ll) and l for short tail (ll)
feather color: b for blue feathers (bb and bb) and b for white feathers (bb)< br />
part 1: crossing beak color and tail-feather length< br />
cross a yyll (heterozygous parent with dominant traits) with yyll (homozygous parent with recessive traits). look at the number of phenotypes of the f1 generation: < br />
yyll: 400< br />
yyll: 100< br />
yyll: 100 < br />
yyll: 400< br />
2. how far apart are y and l? give your answer in map units. (hint: add the numbers of the two recombinant types, divide by the total number of offspring, and multiply by 100.)< br />

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
