This would be just a genetic or inherited condition.
Sickle cell anemia and cystic fibrosis are carried on autosomes (chromosomes other than the sex chromosomes). Probably too many to list . . Right now, off the top of my head, I can think of Down's Syndrome (21st chromosome) and the "cri du chat" (5th chromosome) . . .
The gene that causes cystic fibrosis is located on chromosome 7, which is an autosome, not a sex chromosome.

The Y chromosome closely resembles many of the other chromosomes. What did you have to do to determine that it was the Y chromosome?
The chromosomes you are referring to are called autosomes.
The x chromosome is one of the sex chromosomes, the other being the y chromosome. In mammals there are two of the sex chromosomes in each organism. Females generally contain two x chromosomes, and males contain one x chromosome and one y chromosome.
Chromosome pair 23 in humans is the pair of sex chromosomes. In females, both sex chromosomes are the X sex chromosome, and in human males one sex chromosome is the X and the other is the Y chromosome.
The 23rd pair of chromosomes are the sex chromosomes. In female humans, both sex chromosomes are homologous, and characterized as XX. In male humans, one sex chromosome is an X chromosome and the other is a much smaller, nonhomologous Y chromosome, and is characterized as XY.
Hemophilia is a sex linked recessive trait, meaning that it must be present on both X chromosomes in women while just the one X chromosome in males (because their Y chromosome lacks the necessary gene). Since the women displays the trait, both of her X chromosomes must have the recessive trait. One chromosome came from the only X chromosome her father had, so her father was also a hemophiliac. Her mother on the other hand had two possible chromosomes to donate, so she was either a recessive carrier (meaning only one of other chromosomes had the allele) or she was a complete hemophiliac with the allele on both chromosomes..
