Answer 1

The correct option is A A, B and C

sickle cell anemia is an autosomal recessive inherited disorder in which both parents pass on the defective gene to their child. This is a disease in which the red blood cells are sickle in shape and can obstruct blood vessels. Symptoms of sickle cell anemia include low levels of red blood cells (anemia), fatigue, shortness of breath, yellowing of the skin and bone, chest, stomach or joint pain. Sickle cell anemia can also lead to frequent infections, delayed growth, pale skin, swelling of the hands or feet and face, arm or leg weakness. Haemophilia is a X linked genetic disorder. An extra one chromosome seen along with diploid number of chromosomes. Holandric genes are Y linked gene characters seen only in males. Thus, option A is correct and other options are wrong.
