Answer:
XnY
Explanation:
II-2 is a male so the genotype must have a Y in it. Majority of the other options do not have Y, so they are incorrect. Because the individual is male, the father has passed a Y chromosome, while the mother has passed an X chromosome. The X chromosome is Xn because the mother is hemolytic, which is a recessive trait. So both the mother's X chromosomes carry the hemophilia trait.
The answer is either A or C

I breathed heavily and hugged Dad one last time. I was going to miss him. Dad was serving in the Union, and he was leaving us behind. Mom was crying and hugging him all she could. We eventually let him go, and he went off to war.
My brother yelled in anger at me. "NO!" He said. I wanted to cry as much as I did when Dad left. "The Confederacy is better than the Union!" He yelled. He was 22, so he could serve in the army. And sadly, he did.
Answer:No one knows exactly how many species live in the world's tropical rainforests — estimates range from 3 to 50 million species — rainforests are the undisputed champions of biodiversity among the world's ecosystems, containing far higher numbers of species on a per-area basis relative to sub-tropical, temperate, and boreal ecosystems. For example, whereas temperate forests are often dominated by a half dozen tree species or fewer that make up 90 percent of the trees in the forest, a tropical rainforest may have more than 480 tree species in a single hectare (2.5 acres). A single bush in the Amazon may have more species of ants than the entire British Isles. This diversity of rainforests is not a haphazard event, but is the result of a series of unique circumstances.
