In a species of garden snail, the allele causing a banded shell (bb) is recessive to the allele for unbanded shell (bo). similarly, for shell color, yellow (cy) is recessive to brown (cbw). a banded, yellow snail is crossed with a homozygous brown, unbanded snail. the f1 are then crossed with banded, yellow snails (i. e. in a testcross). what will be the results of the testcross if the genes for color and bands are linked and 20 map units apart?

The management of a supermarket wants to adopt a new promotional policy of giving a free gift to every customer who spends more than a certain amount per visit at this supermarket. the expectation of the management is that after this promotional policy is advertised, the expenditures for all customers at this supermarket will be normally distributed with a mean of $95 and a standard deviation of $20. if the management wants to give free gifts to at most 10% of the customers, what should the amount be above which a customer would receive a free gift?
