According to Catholic scholars, does Gen. 1:27b ("male and female he created them") follow from Gen. 1:27a ("God created man to his own image")?

Gen. 1:27 (NRSV-CE) says: > So God created humankind in his image, in the image of God he created them; male and female he created them. See that the author of Genesis puts two accounts: one, on the creation of humankind in God's own image and the second, on the creation of humans as male and female, in one single verse as if in one breath. Note that the two parts are not joined (or separated) by a conjunction like `and', *therefore* or *but*, but are only divided by the punctuation of semicolon. One could be pardoned for doubting if the second part of Verse 27 owes its origin to the first part . In other words, does the “image” of God in which mankind was created, contain primordial elements of both masculinity and femininity? My question therefore is: **According to Catholic scholars, does the second part of Verse 27 of Genesis 1 have any connection to the first part?**
