Question

On which kind of chromosome, the autosomes or the sex chromosomes, are defective genes causing, Thallasemia, colour blindness and Haemophilia located?

Answer 1

Explanation:

In humans there are two types of chromosomes.

1. Sex chromosomes
2. Sex chromosomes Autosomes

there are also many diseases which are genetical.

some of them are Thallasemia , colour blindness, and Haemophilia .

these all are genetical diseases and the defective genes which causes such diseases are located on the sex chromosomes.

specially these all genes are located on the X chromosomes ..

these all diseases are X linked recessive deseases.

Answer 2

Answer:

Defective genes causing, "Thallasemia, colour blindness and Haemophilia".

Explanation:

• "Thalassemia" is a blood disorder, the effected body produces an abnormal or an insufficient quantity of haemoglobin.  
• Haemoglobin is the "oxygen-carrying protein" in red blood cells. The disease leads to the destruction of big amounts of red blood cells, leading to anaemia.
• "Color blindness" is a genetic condition induced by a difference in the response to certain colors of one or more light-sensitive cells discovered in the eye's retina.  
• Haemophilia is triggered by a genetic mutation. Haemophilia A is caused by a factor VIII gene mutation, so this clotting factor is deficient.
• Haemophilia B outcomes from a 'factor IX deficiency' due to a gene mutation.
