Hemophilia was common during the 1800s in the royal families of Europe, whose members often intermarried. Queen Victoria of England was a carrier of the trait. She had one X chromosome with the allele for normal blood clotting (XH) and the other with the defective allele (Xh). Because she did have one normal dominant allele, her blood clotted normally. Her husband, Prince Albert, was completely normal for this trait. He had one normal allele on the X chromosome (XH) and a Y chromosome with no allele related to blood clotting (Yo). Eighteen of Queen Victoria’s 69 descendants were carrier females or hemophiliac males. Crown Prince Alexis of Russia was one of these hemophiliac descendants. His affliction indirectly contributed to the overthrow of the monarchy in Russia. What would the ratio of phenotypes of Victoria and Albert children be?

This map shows how climate change might affect precipitation patterns in the great plains of the united states by the end of this century. brown shoes a decrease in percipitation, and blue shows an increase. the maps differ based on the predictive levels of green house emissions. the maps shows that northern area should get a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.southern areas show a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.to use these maps to prepare for natural disasters in the great plains, scientist need to ask? a. how many tons of emissions were used at the basis of the map.b. which types of fossil fuels are used in the great plains c. if you think the above is wrong it's probly c the question is cut off
