Drosophila (fruit flies) usually have long wings (+) but mutations in two different genes can result in bent wings (bt) or vestigial wings (vg).
If a homozygous bent wing fly is mated with a homozygous vestigial wing fly, which of the following offspring would you expect?

a. 1/2 bent and vestigial to 1/2 normal
b. 1/2 bent and 1/2 vestigial flies
c. 3/4 bent to 1/4 vestigial ratio
d. all +bt +vg heterozygotes
e. all homozygous + flies

How do water’s relative densities as a solid and a liquid differ from that of most other substances? water’s solid and liquid forms have different densities, while most other substances have solid and liquid forms with similar densities. water’s solid and liquid forms have similar densities, while most other substances have solid and liquid forms with different densities. water’s liquid form is less dense than its solid form, while the opposite is true of most other substances. water’s solid form is less dense than its liquid form, while the opposite is true of most other substances.
