Okay my question has to do with a pedigree shown in an illustration. Since I can't show the illustration I'll do my best to describe it: There's a mother and a father and they have 4 kids: 2 boys, 2 girls. Circles represent females and squares males. A darkened shape means the individual is affected by a genetic disorder. Kid #3 (a girl) has a genetic disorder. Now here are the questions:

a.What are the genotypes of both parents? Is this disorder dominant or recessive? Explain your reasoning.

b.What is the genotype of the affected child? (Kid #3)

c.What are 2 benefits that Kid #3 could expect from genetic counseling and testing?
