Kolean clearly states that there are 2 X chromosomes in the female's cells at the beginning, add 22 pairs to this and you start with 24. Drop one of these and you get 23 multiply this by 2 and the result is 46! and only one of these 46 is a sex chromosome. Which means that if 44 form a pair then there is 1 half chromosome floating around looking for a partner

first mistake

a pair of chromatids equals a chromosome and not a pair equals a chromosomes

second mistake

22 pairs of chromosomes are there and not 22 pairs of chromatids. do you get my point?

third mistake

a carried over mistake

22 pairs= 44

+ 2 X chromosomes

= 46

this is the right thing

and now let's consider your second part in which you try to pove your thoughts to be true

mistake number 4

from where did you get 44? you have forgotten that there are 46 chromosome and not 46 chromatids

mistake number 5

\basically you are not considering 1 chromosome as 1 out of 46 you are taking it to be equal to 2.

and that's how you get the 1/2 chromosome floating

it isn't what you do that matters but it is how you do it

OK, so what is spine in accordance to you?

How do you divide the Czech alphabet?

*Cis*or*trans*? That's what matters.Wikipedia definitions suck. It is why we are having this discussion. It begs for editors who are working scientists instead of rehashers. I sincerely hope that climate change does not fall into the hands of a wikipedea group as is being suggested to replace the IPCC.

The Czech alphabet is not used much. There are 26 basic sounds i.e. letters that do not have accents or combinations like ch. I am not familar with the Japanese alphabet but I am pretty sure that you make the same sounds as the rest of us.

The Human Genome project shows 24 chromosomes 22+X+Y. If that ads up to 23 then when you multiply this by 2 you are back to 46. In this number, there would have to be 2X's and 2Y's. This would then mean that you would have 42 left to make pairs and you would be left with 21 pairs and 4 sex chromosomes. Jack Bean was right at the start, when he quoted Wikipedia. There are 46, and 2 of those are (single) sex chromosomes. This is my last post on this topic, thanks guys.

Really? I would expect to divide it into e.g. 36 parts, if is it supposed to be so intelligent.

Notably, the day and hours has nothing to do with circle and clocks, but never mind...

"see we have 23 pairs of chromosomes in total."

This is not truth.

Well, as a matter of fact: it is true.

It is not too hard for you to check this. We all have 23 chromosome pairs. The last 23d pair is made of sex chromosomes (X+Y or X+X depending on the individuals sex).

22 autosomal chromosome pairs, 1 sex chromosome pair.

If you accept that there are 46 chromosomes of which 2 are sex, then 22pairs +X+Y=24. The initial mistake that was made is holding back the science. There are 24 hours in a day. There are 24 vertebrae in our spine. There are 12 zodiac signs which we feel through 2 organs giving us 24 Chi Chi. It is important that we wake up to the fact that we have evolved on a planet which spins and travels round the Sun at speeds of over 100000 km/hr.
