:Match the columns :
Column $I$ |
Column $II$ |
$(a)$ Sickle cell anaemia | $(x)$ Homogentisic acid |
$(b)$ Alkaptonuria | $(y)$ Melanin pigmentsare absent |
$(c)$ Albinism | $(z)$ More amount of phenyl alanine |
$(d)$ Phenyl Ketonuria | $(w)$ Defective haemoglobin |
$A$ : The posssibility of a female becoming a haemophilic is extremely rare.
$R$ : Mother of such a female has to be carrier and father should be haemophilic
