Jesus was never a mere man....nor was he born in sin as his origin was heavenly not earthly.
Jesus could not carry a single strand of Adam’s DNA because the life he lost for his children was sinless and no human born from sinful Adam could pay the set price of redemption, but a sinless man. Hence Jesus had to come from heaven and be born of a human woman without any of Adam’s DNA being involved.
He was God’s Son who came into the world through a human agency....Mary.
He was born sinless to pay Adam’s debt. God’s law demanded justice, in that a life taken had to be atoned for by a life given in recompense. As ‘in Adam all must die, so in Christ all can be made alive’....but it’s not automatic....you have to accept Christ as your savior and serve the God that he served. (Acts 4:27, 30)
It means becoming an imitator of Christ. (1 Pet 2:21)
As stated before, the WTS / JW error (borrowed somewhat from Catholicism, though rejecting it in other parts), removes Jesus from being able to be the substitute and/or example for any of humanity.
Jesus came in "the likness of sinful (fallen) flesh" (nature), as per Romans 8:3
Rom 8:3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
Where was "sin condemned"? "in the flesh". In the "flesh" of who? "God['s] "own Son" (aka Jesus). In other words, Jesus was able to "condemn sin" because He as "God ... manifest in the flesh" (1 Tim. 3:16) lived a life in "sinful flesh" and yet was "without sin" (Heb. 4:15 KJB) in that perfect life. He is the substitute and also example, that each of us, who live in the same flesh, sinful (fallen) flesh can live by the same Spirit He lived in, being the Holy Spirit (of which His mind was born of; Luk. 1:35 KJB). Do not confuse the two, "flesh" and "spirit" (mind), as Jesus in John 3 is clear about that separation. See this chart (pages 121-122) -

The Psalms (of David, the type of Christ) says the same thing:
Psa_51:5 Behold, I was shapen in iniquity; and in sin did my mother conceive me.
This Psalm (51), as other scriptures, point to the real David, or Jesus (Jer. 30:9; Eze. 34:23-24, 37:24-25; Hos. 3:5 KJB, see Jhn. 5:39; Luk. 24:27; Act. 3:18 KJB, &c.). To be born with sinful flesh, is not to be born a sinner. Sin is the transgression of the Ten Commandments / Law of JEHOVAH Elohiym (1 Jhn. 3:4; Rom. 7:7,14; Jam. 2:80-13 KJB, &c.)
not simply being born (that is a Roman Catholic ideology, comes through "Original Sin" dogma, which is why they needed "Immaculate Conception" (Mary needed to be sinless by her mother 'Anne') dogma, and later "Impeccability" dogma, &c.). Sin is a trangression (commission or omission).
To deny that Jesus came in that "sinful (fallen) flesh" nature of Adam, after sin, is the ideology of "antichrist":
1Jn_4:3 And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.
2Jn_1:7 For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist.
It means, that Jesus could not save any person born with sinful (fallen) flesh nature, since the WTS / JW, and others like Roman Catholicism strip Jesus of that attribute. Salvation means nothing then, since there was no salvation from anything, since the "sinful (fallen) flesh" of Jesus is removed from Him.
Yet scripture is clear:
Heb_2:16 For verily he took not on him the nature of angels; but he took on him the seed of Abraham.
Angelic beings, have an unfallen flesh nature. Jesus did not take that nature in becoming human. He instead took on "the seed of Abraham", and "seed" has a specific DNA structure / profile. Abraham was a sinner. Thus Abraham's physical descendants, as Jesus was, is also physically of that same fallen nature in His humanity.

Moreover the scriptures state these same things again and again:
Rom_1:3 Concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh;
Gal_4:4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,
2Ti_2:8 Remember that Jesus Christ of the seed of David was raised from the dead according to my gospel:
The law of heredity in human fallen flesh, through Mary, through David, through Abraham, through Noah, through fallen Adam (&c), is what Jesus took upon Himself in becoming a man. All children are born with sinful (fallen) flesh after Adam / Eve sinned. The very word "seed" comes from Gen. 3:15, and the nature itself also shown by that fallen "woman" and by the fallen flesh of the lambs in Gen. 3:21.
Thus "made of a woman" (Mary, descedant from Eve, the mother of all living, who came from Adam (thus "one flesh" of mankind, unfallen in the beginning, now fallen through sin):
1Co_15:39 All flesh is not the same flesh: but there is one kind of flesh of men, another flesh of beasts, another of fishes, and another of birds.
Jesus could not be a creature (which is already amenable to God's law and subject under it, their life not being their own). Jesus could not be with sinless flesh (since that would prove nothing, be an example for no one on earth after Adam's sin, and by no means help anyone who is with sinful flesh overcome anything, since the devil would just claim Jesus had advantage in flesh). Jesus could not be absent of Adam's DNA (as the law required a life and blood (in which is DNA), and only a life of Adam's DNA, and yet also before Adam as Head over humanity as Creator, and one of infinite life, greater than length of death (1st and 2nd)). Thus only the Alpha and Omega could redeem.
The WTS / JW 'gospel' is no gospel at all, cannot save anyone, since their flesh is differing than Jesus' flesh, and they claim not to bother with the Ten Commandments in their 'NC' anyway (in brief), and so, presently go about proclaiming a self-righteousness (apart from God's righteousness; Psa. 119:172), or a way to exist without obedience to God's ways, which is an impossibility.
2Pe_2:19 While they promise them liberty, they themselves are the servants of corruption: for of whom a man is overcome, of the same is he brought in bondage.
So, the WTS/ JW will talk about "saviour", "salvation", but their definition is void of the scriptural definiton of salvation:
Mat_1:21 And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.
Jesus did that in the likeness of sinful (fallen) flesh, and yet did not sin in that flesh by the Holy Ghost, by grace through faith! That is the victory. That is the Everlasting Gospel. Whatever it is that the WTS / JW are selling, it isn't the real gospel. I am not speaking of individual persons caught up in that system, or even of A.J. here. I am speaking of a system of belief / practices that will lead to death, and only death. They do not accept Jesus as the I AM of Exo. 3.
Joh_8:24 I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins.
Thus, while a WTS / JW member may say that Jesus is "Lord", they only mean it in such a way as like a kingly ruler, and not what the scriptures mean by it, citing OT, referring to Jesus JEHOVAH.
Php_2:11 And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
That "kyrios" ("Lord") is simply the NT way of Paul citing the OT Hebrew "JEHOVAH", but covering it from "Adonai" (thus translating to Kyrios, "κυριος" in the NT koine Greek) over JEHOVAH as many Jews then did at the time.
Isa 45:21 Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the LORD? and there is no God else beside me; a just God and a Saviour; there is none beside me.
Isa 45:22 Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else.
Isa 45:23 I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return, That unto me every knee shall bow, every tongue shall swear.
Isa 45:24 Surely, shall one say, in the LORD have I righteousness and strength: even to him shall men come; and all that are incensed against him shall be ashamed.
Isa 45:25 In the LORD shall all the seed of Israel be justified, and shall glory.
In other words, at present, only a born again person will acknowledge that Jesus is the LORD- JEHOVAH. WTS / JW members will never do that because of their indoctrination to the contrary.
