There are various very important conclusions to draw from this.
The first great conclusion is that God can and did create at least one gene at one point in time.
Secondly, the significance of the Virgin Mary: She actually supplied the DNA of the human body of God Incarnate.
If Mary alone provided the genome of the Christ, the Messiah, God Incarnate, she must have been chosen very carefully. She would impart to the Son of God her body type, physiological health, personality and intelligence. This is an insight into the specialness of Mary.
The Gospels testify to the closeness of Jesus to Mary, Mary to her son. If they were the male and female version of the same genome, with identical DNA, this in part, would explain their closeness. They would have the same physical type and personality traits in everything except in masculinity and femininity.
