Just to amplify on the link Leolaia posted, Ron Wyatt (now dead) claimed to have found a sample of Jesus' blood (!) on the Ark of the Covenant (!!):

Wyatt claims to have found the Ark of the Covenant in Jerusalem in a secret cave under the actual spot where Christ was crucified, and it had Jesus’ blood all over it (the blood had dripped down from the cross).
Whilst in the chamber, Ron noticed a dried, black substance in an earthquake crack in the roof, above the Ark of the Covenant. He noticed that this black substance was also on the lid of the cracked stone casing. Obviously, this substance had dripped from the crack in the roof, and provision had been made for it to land on the Ark of the Covenant, as the stone lid had been cracked and moved aside. Ron wondered what substance could be so sacred, that God made provision for it to land on the Mercy Seat of the Ark of the Covenant. He remembered the earthquake crack at the foot of the cross hole, and suddenly an awesome realization as to what had happened, came over him. Ron traced the earthquake crack, and indeed it was the same crack as the one at the cross hole. The dried black substance in the crack was tested and proved to be blood, apparently the blood of Jesus Christ. The Bible says that when Jesus died there was an earthquake and the rocks were rent (Matt. 27:51). A Roman soldier speared Christ in His side in order to make sure He was dead, and blood and water poured out (John 19:34). Ron discovered that this same blood and water poured down through the earthquake crack and fell upon the Mercy Seat of the Ark of the Covenant.
Since the blood was dried, he had it rehydrated and then, allegedly, had it tested (where are those tests? No one seems to know – surprise, surprise). And here’s the result:
Human cells normally have 46 chromosomes. These are actually 23 pairs of homologous chromosomes. In each pair of chromosomes, one of the pair is from the mother and the other member is from the father. Therefore, 23 chromosomes come from the mother and 23 from the father. In each set of 23, 22 chromosomes are autosomal and one is sex-determining. The sex-determining ones are the X chromosome and the Y chromosome. Females are XX, so they can only contribute an X chromosome to their offspring, whereas males are XY, which allows them to contribute either an X or a Y. If they contribute an X, the child is female, whereas if they contribute a Y, the child is male. The fascinating finding in this blood was that instead of 46 chromosomes, there were only 24. There were 22 autosomal chromosomes, one X chromosome and one Y chromosome. This evidences that the person to whom this blood belonged to had a mother but no human father, because the normal contribution of paternal chromosomes is missing.
So NONE of this outrageous fictional stuff is verifiable, since where is the Ark of the Covenant currently? Finding the Ark would be a HUGE archaeological discovery, so where is it? And where is that sample of Jesus' blood? That would be HUGE news, and of extreme interest to the scientific and medical community. However, it doesn't take a rocket scientist to conclude the guy was telling tale tales, a scammer.
Leolaia said-
So....Jesus apparently was a mutant and his Y chromosome came from, um, God?
That's the suggestion. If true, it WOULD explain all those Bible passages that noted how Jesus looked like Mary's spitting image, more like her side of the family than Joseph's. Oh, there's no such passages, you say?
From Wikipedia, organisms having an abnormal number of chromosomes in their cells is a condition called Aneuploidy, a type of chromosome abnormality. An extra or missing chromosome is a common cause of genetic disorders (birth defects). Some cancer cells also have abnormal numbers of chromosomes.
As Wikipedia explains, most fetuses with such abnormalities are spontaneously aborted by the mother, as the fetus is not viable (most abnormalities in humans are limited to a single missing or extra copy of a chromosome, but missing the ENTIRE SET of 22 autosomes from the father? Nonsense. Of course, "God did it" covers all such miracles).
Still, it's interesting that Wyatt would imply Jesus had a chromosomal trait in common with that of many cancer cells.
