Ageing of YDNA method right?

Ageing of YDNA method right?

i feel the way the y dna grouping and ageing isnt following a right approach.
assume the following case.


1.A homo erectus of india who had continous evolution and inter breed with modern homo sapeins

will have homo erectus DNA in 1-2% and 98% homo sapiens DNA.

2. A homo sapiens of Africa who evolved from oldest homo sapiens with 100% homo sapiens DNA

now here 2% dna of 1st case is older than 100% homo sapiens of 2nd case
but we are neglecting 2% homo erectus dna and in timeline we place

case 2 older than case 1 which isnt right.


he are ageing the dna of hiegher % YDNA and not the least % YDNA

if we list ageing of least % DNA then case 1 will be oldest

i am expecting opinion on this

Y DNA doesn't mix. If anyone had a Homo erectus Y chromosome it would stand out like a giant flashing neon sign.

it doesnt mix but % wise compositin reduce

after 80k years of inter breed a homo erectus descandants from india got 2% dna of homo erectus and 98% dna of homo sapiens
since homoerectus % is too less they dont consider what if the % is very minute like .1% and ppl neglect it


this is what happens a non continuous group in africa is considered as oldest group than a continuous group in india
this is mistake .
