Nobody knows why there are women and there are men?

[andyoldlabour]

According to Ellie Mae O'Hagan of the CLASS think tank:

"I don't know why some people are women and some people are men, nobody on this panel does"

Crikey, I know things are bad, but I didn't know we had reached Defcon 1 already.

Err, I think your wrong. Sex diamorphism is the mechanism evolution has fallen on to mix genes. Organisms that dont mix genes repoduce through dividing and are basically clones of the parent, like viruses.

Having mixed genes, that is not being a clone of one parent, proved useful to overcoming pathogens that are also evolving.

It isn't the male that solely determines the sex of a child- XX is a girl and XY for a boy - the chromosomes need to combine and that assignment is one last to be made.

Well, women are XX so always pass on an X. Have a guess where the other X or Y comes from. If it's not from the woman it must be ...

In her world there is no reason to avoid incest, is there?

Most don't consider single cells single cell organisms as being living things- and viruses certainly aren't some viral assemblies includw proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. In cell division a parentcelldivides into two or more daughter cells usually occurs as part of a largercell cycle. Ineukaryotes, there are two distinct types of cell division; a vegetative division, whereby each daughter cell is genetically identical to the parent cell called mitosis and a reproductive cell division, where the number ofchromosomesin the daughter cells is reduced by half to produce haploidgametes ..
to go back to thecell cycle, mitosis in which, replicatedchromosomesare separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained. Usually, mitosis is preceded by DNA replication and followed by cytokinesis; which divides thecytoplasm,organellesandcell membraneof one cell into two newcellscontaining roughly equal shares of these cellular components.

Really?

Well that was very informative.

To no particular end

Yes it is the male that always and solely determined the sex.

Why are you giving cell division lessons @SCR0071?

All I am saying is that until the X is combined with the X or Y there is no determination of sex and in human inheritance that chromosomal combination is made at the end of the selection of the 23 from each parent.

Why are you giving cell division lessons *@SCR0071*?

I was wondering the same thing. Given the mistakes it's more amusing than informative.

Would consider it a lecture- I understand what cells are and do as professionally I model virus capsids from atomic cross sections

@SCR0071

sexual dimorphism, is a term for the differences in appearance between males and females of the samespecies it has nothing to do with inheritance- and you don't mix genes - they come as a sub set of chromosomes which do get mixed finally with regard to pathogens- how often do you find an individual with a one off natural immunity to a disease? Not very often that is genetic- it is your immune system that deals with pathogens.

Oh dear me - this is also known as gamete dimorphism.

Please stop trying to teach yourself biology from whatever resource you are currently using - maybe enrol in a class or do an OU course or a biology GCSE/A-level instead.

I'd rephrase as 'why are you copying and pasting off the internet with limited understanding of what you're pasting, *@SCR0071*?'

There are a few basic biological inaccuracies in what SCR0071 has said.

I'll start by clarifying that viruses are not single-celled organisms - they are entirely lacking a cell. And that single-celled organisms are most certainly considered to be living things by any biologist with even half a clue.

I'm also slightly puzzled as to why the 'lesson' in cell division was relevant.

Err, what…?

Considering you seem to be conflating viruses with cellular organisms, I find this rather difficult to believe!

Or is it that you're a computational scientist rather than a biologist, and are somewhat stretching the limits of your professional knowledge?

@Igneococcus

Every living thing on the planet inherts its chromosomes from both parents

Poor Prokaryotes, overlooked again, despite that they vastly outnumber all those Eukaryotes with their fancy-schmancy sexual reproduction (and do all the important stuff), pffft.

Our friend has told us they aren’t living things though - all those bacteria, archaea, fungi….no hope for them!

Dead, dead, and never called me “mother”

@SCR0071

All I am saying is that until the X is combined with the X or Y there is no determination of sex and in human inheritance that chromosomal combination is made at the end of the selection of the 23 from each parent.

Sorry but this is totally wrong. I still think you are a bit confused.

Until the X is combined with the XorY there is nothing, as in conception has not happened.

Also there is no selection as the egg and sperm have their 50% DNA and it is all used to make the new individuals new set of DNA.

Careful now, your ignorance is showing.

🤣🤣🤣🤣

Ay me…

To point out that the Eukaryote reproductive process achieve the same rest in human reproduction which was disputed

your shitposting on a Thursday nite (like me) but yours is funnier.

@lottiegarbanzo

'Don't know much about history, don't know much biology...' Literally! Lol.

brilliant

I didn't day that viruses were singled celled - I said they were not living

I’d love to know more about how you model viral capsids from atomic cross sections
