Why are colorblind and hemophilia rare in females?
This is because: Males have only 1 X chromosome, from their mother. If that X chromosome has the gene for red-green color blindness (instead of a normal X chromosome), they will have red-green color blindness. Females have 2 X chromosomes, one from their mother and one from their father.
How are hemophilia and red-green colorblindness inherited?
Genes are inherited from our biological parents in specific ways. One of the basic patterns of inheritance of our genes is called X-linked recessive inheritance.
Why are haemophilia and Colour blindness usually seen in males?

Can you have a successful pregnancy after 2 miscarriages?
Yes, you have a good chance of having a successful pregnancy in the future. Most women who have had two miscarriages go on to have a healthy pregnancy.

Why would a woman have multiple miscarriages?
Recurrent early miscarriages (within the first trimester) are most commonly due to genetic or chromosomal problems of the embryo, with 50-80% of spontaneous losses having abnormal chromosomal number. Structural problems of the uterus can also play a role in early miscarriage.
