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

Answer» Correct Answer - D The sex linked recessive diease shows its transmission from unaffected carrier female to some of the male progeny e.g., haemophilia. The heterzyous female (carrier) of haemophilia may transmit the disease to sons. The possibility of a female becoming a haemophilic is extremely rare because mother of such a female has to be at least carrier and the father should be haemophilic. |
