Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of papaya sex inheritance.
Step 2: Key Formula or Approach:
Papaya has three sex types: Female (XX), Hermaphrodite (Hh), and Male (hh).
When a female (XX) is crossed with a hermaphrodite (Hh), the progeny ratio is 1 Female : 1 Hermaphrodite.
Step 3: Detailed Explanation:
Female parent: XX
Hermaphrodite parent: Hh
Gametes: Female = X; Hermaphrodite = H or h
Progeny: XH (Hermaphrodite), Xh (Female)
Thus, the ratio is 1 Female : 1 Hermaphrodite.
Final Answer:
