XY Chromosome is identified as male. XX Chromosome is identified as female. Do Lesbians get YY instead?

Just a thought I wondered when a Cosmic Ray zapped my brain. Genome scientists have postulated

that male-male sexuality might be related to the XY chromosome pair where the Y factor is minimal in

relation to the X side factor. My thought was that XY = male & XX = female so "could" xX or Xx =

lesbian genetically ( YY was probably the wrong term to use) ?

All cisgender lesbians are XX chromosomes.

YY is some mythical fairy creature or something.

So this means that GOD did not fix chromosome YY to human being ,then being Lesbians is the work of satan then.

Some males are XX and some females are XY

Every chromosome has at least one X because the female gamete always has an X. As for lesbians, that is something you feel, not something in your DNA

YY? Such a creature doesn't exist, and as they said of that bizarre transporter accident in the first "Star Trek" film, "it wouldn't live long".

YY isn't a viable genotype.

Stay in school.

Apparently you missed the Biology course in yer schoolin'

Sexual preference is not at all reliant on chromosomes.

No, they still got XX.
