Ebony body, held-out wings and sepia eyes are all recessive and all on chromosome 3. the coefficient of coincidence for chromosome 3 is 0.5. a homozygous ebony male is mated to a homozygous held out wing and sepia eyed female. the f1 are wild-type. an f1 female is test crossed to a fly that is homozygous for all three recessive alleles and they produce 1000 progeny. if ebony and held-out are separated by 12 map units, and held-out and sepia are 14 map units apart, and if the order of these loci is ebony, held-out, and sepia: how many ebony, sepia (but not held-out) progeny are expected from this test cross?

4.06 hc)a five-year review of threats to the southern resident orca population of the united states concluded that the top threats were prey availability, contaminants, and effects from recreational and whale watching vessels. further down the list are oil spills, disease, and effects from commercial vessels not targeting whales. how might this list be different if it were for transient whale populations, which have a larger average population size and live farther offshore in open waters? a)the transient population is more likely to be affected by contaminants. b)the transient population is less likely to be affected by whale watching vessels. c)the transient population is more likely to be affected by disease. d)the transient population is less likely to be affected by prey availability.
