Final answer:
The loss of Iphigenia impacts Clytemnestra and eventually Agamemnon as Clytemnestra blames Agamemnon for Iphigenia's death and seeks revenge.
Step-by-step explanation:
The loss of Iphigenia impacts Clytemnestra and eventually Agamemnon in several ways. Clytemnestra, as Iphigenia's mother, is devastated by the loss of her daughter. This loss leads Clytemnestra to harbor deep anger and resentment towards Agamemnon, as she believes he is ultimately responsible for Iphigenia's death. As a result, Clytemnestra plots her revenge and eventually kills Agamemnon when he returns from the Trojan War.
