I don’t know where to post my questions, so I’m posting them here.
My first question is, what was meant exactly by Genesis 2:24?

Genesis 2:24 That is why a man leaves his father and mother and is united to his wife, and they become one flesh.

In Mark 10:5-9, Jesus couples Gen 1:27 with Genesis 2:24 and following Gen 1:27 (their being made in God’s image) is God’s command to them to be fruitful and increase in number:

5 “It was because your hearts were hard that Moses wrote you this law,” Jesus replied. 6 “But at the beginning of creation God ‘made them male and female.’[a] 7 ‘For this reason a man will leave his father and mother and be united to his wife,[b] 8 and the two will become one flesh.’[c] So they are no longer two, but one flesh. 9 Therefore what God has joined together, let no one separate.”

27 So God created mankind in his own image,
in the image of God he created them;
male and female he created them.
28 God blessed them and said to them, “Be fruitful and increase in number;

My second question is then, is it possible that what was meant by “one flesh” in Gen 2:24, was the offspring of male and female, since children are born with chromosomes from each parent?? Does “one flesh” have to do with offspring?
I would appreciate what anyone has to offer. I mean, even partners never operate as “one flesh” all the time because there is always differences somewhere, so what of their children?? Could it be that offspring is what is meant by “one flesh”? What are your thoughts/ideas?
