Autosomal dominant disorder || Pedigree solution || Genetics |

Given below is a pedigree showing the inheritance of an autosomal dominant disorder. The genotypes of person 1, 2 and 3 in this family tree are:

Pic out the correct stataments (I) Haemophilia is a sex-linked recessive disease (II) Down's syndrome is due to aneuploidy (III) Phenylketonuria is an autosomal dominant gene disorder (IV) Phenylketonuria is an autosomal recessive gene disorder (V) Sickle-cell anaemia is an X-linked recessive gene disorder

Pick out the correct statements: (i) Colour blindness is a sex - linkes recessive gene disorder (ii) Klinefelter's syndrome is 18^(th) chromosomal trisomy (iii) Phenylketonuria is an autosomal dominant gene disorder (iv) Down's syndrome is due to aneuploidy

Sickle cell anemia is (a) Autosomal dominant inheritance (b) X-linked recessive inheritance (c) Autosomal recessive inheritance (d) X-linked dominant inheritance

Name one autosomal dominant and one autosomal recessive. Mendelian disorder in human.

Name one autosomal dominant and one autosomal recessive. Mendelian disorder in human.

Name one autosomal dominant and one autosomal recessive Mendelian disorder in human.

In the following pedigree chart, state if the trait is autosomal dominant, autosomal recessive or sex linked. Give a reason for your answer:

Name a blood related autosomal Mendelian disorder. Why is it called Mendelian disorder? How is the disorder tansmitted from parents to offsprings?

Given pedigree belongs to autosomal recessive disorder , which of the following represents parental genotypes correctly ?
