Question

Study the pedigree chart. ( picture above)

Answer 1

Answer: The trait is recessive. the parents of A were both carriers

Explanation: The correct answer should be the trait is recessive.

Since we can only see A mothers tree and she is not affected by the trait she is a carrier.

Unfortuately, the tree does not show her father's side of the tree so we can only "assume" based on the options that he also is a carrier of the trait.

So answer it will be "The trait is recessive. the parents of A were both carriers"
