In goats, a beard is produced by an autosomal allele that is dominant in males and recessive in females. We’ll use the symbol Bb for the beard allele and B+ for the beardless allele. Another independently assorting autosomal allele that produces a black coat (W) is dominant over the allele for a white coat (w). Give the phenotypes and their expected proportions for the cross between B+Bb Ww male × B+Bb Ww female. Which of the following is not an option phenotype and proportion from this cross?
a. 9/16 bearded, black female
b. 3/16 bearded, black female
c. 1/16 beardless, white male
d. 3/16 bearded, white male
e. 1/16 bearded, white female

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
