Question

Both Thalassemia and colour blindness categorised as Mendelian disorders. Justify.

Answer 1

Yes, both thalassemia and colour blindness are categorised as the Mendelian disorders because

1. Thalassemia is an autosomal recessive condition affecting red blood cells. Thalassemia is characterized by inadequate or non-production of one hemoglobin component. Mutations in the portion of the DNA that serves as the template for protein creation might lead to inadequate or non-production of certain components. A mutation can present on one chromosome of a pair.
2. Color blindness is a sex-linked recessive condition where the gene regulating a particular trait is found on the X-chromosome. This is a hereditary illness that causes individuals to have difficulty distinguishing between red and green. This gene has both normal (dominant) and mutant (recessive) forms. Females with color blindness require the defective gene on both X chromosomes, whereas males may be affected if it is only on one X chromosome.
