उत्तर

If a genetic disease is transferred from a phenotypically normal but carrier female to only some of the male progeny, the disease is sex-linked recessive.

Explanation:

If a genetic disease is passed from a phenotypically normal but carrier female to only some of the male offspring, it indicates a sex-linked recessive inheritance. In such cases, females can be carriers without showing symptoms because they have two X chromosomes, and the defective gene is recessive. Males, having only one X chromosome, exhibit the disease if they inherit the affected X from the carrier mother, leading to the disease manifesting only in some of the male progeny. This pattern is typical for diseases like haemophilia and color blindness.

Lipoprotein lipase deficiency (LPLD)is a genetic disorder in which a person has a defective gene for lipase. This leads to high triglycerides, stomach pain, and fat deposits under the skin. It may eventually affect the liver, pancreas and may also cause diabetes. The disorder occurs if a child acquires defective genes from both parents (autosomal recessive). ERT (enzyme replacement treatment) is one of the treatments offered to patients with LPLD.

    1. What procedure is followed in ERT?
    2. What could be one possible drawback of ERT?
  1. How can LPLD be treated using Biotechnology? Elaborate.
