Both sexes are equally useful and are specialised for different but important tasks. Neither gender is 'biologically weaker', not even the blanket octopus where the male is 40,000 times smaller than the female.

Sexual dymorphism does not mean one gender is weaker than the other.

what does this mean?

I am a bioinformatics researcher specializing in non-coding RNA research. First of all, the amount and duplication of genomic material doesn't strongly correlate with organism complexity. Otherwise, the world would be ruled by humble japanese flower plants and amoebas I guess.

But even if you assumed that it does, did you know that only one X chromosome in females is even expressed through the majority of the human life cycle? After embryonic development, a non-coding gene called XIST completely coats the paternal X chromosome, inactivating it. The paternal X chromosome is not expressed in adult women... except for one particular case: cancer. In fact, transcriptional leakage of the paternal X chromosome is a biomarker of breast cancer in women.

I did not,

i seem to be misinformed , i was led to believe that having 2 x was an advantage. i.e things like x linked diseases occur in males but carried by female.

Having 2 x chromosomes just means you have repeats of mostly the same stuff. Men are not missing those genes. If anything women are missing the genetic information found on the Y. According the the drake principle having less genomic material would actually make us more adaptable..

Also a locust has more genes than you so I'm assuming it is more advanced. Males are on average smarter, faster, stronger, more empathetic, less prone to mental illness. On the face of it you would assume men are more biologically fit. On that same token we would assume the sloth to not be biologically fit but it keeps on going. Men and women are about equal numerically so I would say they are equal biologically.

two copies of the same gene can allow for unique dna exploitation that is impossible with just one copy

I thought the y was essentially mostly a remnant or subset of an x. I did not suggest men are missing genes , more that there is redundancy in the event of deleterious mutations.

The Y is a decedent of the typical X chromosome but their departure from one another is as old as mamalia. They would be as genetically unique from one another as my X would be from a platypus's X. At least as I understand it.

You edited your post didn't you?

Ease of derivation doesnt seem to have any bearing on how "weak" an organism is- bacteria out survive humans in many aspects

In fact it may make them stronger, like you said, just look at bacteria.

No.
