What are the possible genotypes of the female child without LCA? ?

Update:

Males are represented by squares. 

Females are represented by circles. 

Filled symbols show individuals who exhibit the trait in question. 

A horizontal line between two symbols represents a mating. 

A vertical line descends from parents to a horizontal line shared by all their offspring. 

A diagonal line through a symbol indicates that person is deceased. 

Roman numerals (I, II, III,…) represent generations. 

Arabic numerals (1, 2, 3,…) represent the birth order of siblings.

    Well, either she is a carrier like both her parents are, or she is not even a carrier.

    I have no idea what LCA is, but your diagram suggests that it is recessive

    There isn't enough info. What kind of gene is this?
