Sex, gender, chromosomes – a study.
Under Virgo moon – a detailed explanation & study
And so…It’s Friday today – Venus’s day, Ray 5 day which oversees Science, Truth & Reality. August 14, 2026 (my mother’s birthday in 1917).
Venus, Ray 5 of science & concrete knowledge, guides, guards & oversees today, Friday.
Where Venus (5) is, Mars (6) is close or nearby – Venus/Mars – the perfect love couple. Intelligence & devotion.

And so…in the news these days the discussion is about gender – men who think they are women playing in women’s sports –
How to be practical with this situation/discussion.
.
Think Science (Ray 5) which gives us concrete knowledge.
It’s all about chromosomes –
So a study today about men & women, about chromosomes
(XY & XX).

There is gender and there is sex.
We are focusing on the sex chromosomes which tells us is a

person a man (XY) or a woman (XX).
A study – under Ray 5 of Science & Concrete Knowledge.
So we know how to have a discussion about these things.

Defining the sexes (not by gender choice but by chromosomes in the DNA) – practical, scientific reality.
Sex – biology, chromosomes.
Gender – in our times, what one identifies as w/out considering biology.
Our focus here is biology, chromosomes (XX & XY).
So…
There are two sexes – male & female (men & women).
Sex is determined by chromosomes. Focus on biology & science.

Men and women share about 99.8% of their DNA.
The core genetic difference lies in the 23rd pair of chromosomes.
Females have two X chromosomes (XX).
Males have one X and one Y chromosome (XY).
This small chromosomal difference controls primary sex determination.

Chromosomes are tiny, thread-like structures inside the center of plant and animal cells.
They are made of DNA wrapped tightly around proteins (histones) – they are made compact to fit into the nucleus of our cells.
Every cell in our body carries copies of our chromosomes (except blood cells & platelets)
This is how cells organize and store our DNA (instructions that make our body work – we each have two copies of instructions to live).
Chromosomes are in pairs.
Humans have 23 pairs of chromosomes for a total of 46 chromosomes. Chromosomes are like books in our DNA library.
The first 22 are called autosomes and the last pair are sex chromosomes.
Each chromosome holds many genes, which act as the instruction manual for your body.
There are 46 chromosomes in each cell in the body.
Chromosomes come in pairs of 23 – 23 from mother, 23 from father.
Chromosomes 1-22 control body traits.
Sex chromosomes: The last pair (the 23rd pair) decides if you are male or female. Females have two X chromosomes (XX), and males have one X and one Y chromosome (XY).
