Answer #1

The pattern of inheritance is x- linked dominant

In autosomal disorder, both the sexes should be equally affected. Here in the question, females are affected more. Therefore it is X linked disorder.
In a dominant disorder, affected children have atleast one affected parent. In the above question, mother is affected and she also has children, few of which are affected. Therefore it is dominant inheritance.
In a recessive trait, unaffected parents should have atleast one affected child.
