ODFOODOHO L11110 Solution
According to the pedigree chart, the parents are unaffected(BUT THE PARENTS HAVE CONSANGUINOUS MARRIAGE-MARRIAGE BETWEEN CLOSE BROTHERS AND SISTERS WHICH ARE COUSINS OF EACH OTHER), therefore both the progeny generations whether male or female affected will possess recessive trait in nature. The affected male will have recessive disease trait whereas the affected female will have autosomal recessive disease trait respectively.
If the parents are cousins or blood related brothers and sisters, then the probability that their children(DIZYGOTIC TWINS) are affected with the disease is 50% with the same percentage of smilarity in their genes.
