Answer:
Hemophilia
Explanation:
This is a disorder in which a blood coagulation factor is missing from the blood, so if the person with the disorder gets even a small injury, he'll bleed a lot due to absence of proper blood coagulation.
It's more common in males than females because females have two X chromosomes. If they have one recessive allelle on one X chromosome, while the other has the dominant allele, they're going to be asyptomatic carriers of the recessive allele.
However, since males have only one X chromosome, having the recessive allele means that they'll suffer from hemophilia. There's no chance of them being just carriers unlike the females.
Microscopes
Before the development of microscopes, the existence of cellular life was unknown. By examining a piece of cork, Robert Hooke first saw and named cells. Antony van Leeuwenhoek was the first person to see living cells.
