How bad must a thread be for dadudemon to be the voice of reason...

You have to look at the chromosomes, women have XX and men have XY. The Y is the lone chromosome, so it's going to come up less often. You're more likely to have a girl than a boy by 75%.There's a graph that can show it easier than I can explain it, but I can't find it and I'm too lazy to draw it out.
Please tell me you are joking.
Well, considering that what you posted was dead wrong...
Women always contribute an X chromosome, so that's not part of the chance calculations - it's set. Men can contribute either. It's just a plain 50/50 chance.
This is not a case where Punnet squares work or are relevant. Though 95% of genetics is more complex than Punnet squares would lead you to believe.

Well, you are incorrect then. If you look at it just from the possibilities it is 50/50. Women always contribute an X chromosome and men either contribute an X or a Y.
In practice it is actually slightly likelier that a y chromosome is contributed. However, due to male fetuses having an incresed mortality rate it even out towards the end of pregnancy.
Further on the thread, as far as i had heard before women slightly outnumbered men, which is down to them on average living longer. However they face incredible problems, especially in third world countries, where killing of women, for example for inheritence reasons, is very common as well as selective abortions. Other examples are the honor killings in middle eastern and latin american countries.

Damn, that's the name of the "graph" I was thinking of.
I am proved wrong. ✅

http://en.wikipedia.org/wiki/Sex_ratio
In humans the secondary sex ratio (ratio at birth) is commonly assumed to be 105 boys to 100 girls (which sometimes is shortened to "a ratio of 105"😉.
In human societies, however, sex ratios at birth or among infants may be considerably skewed by sex-selective abortion.
The CIA estimates that the current world wide sex ratio at birth is 107 boys to 100 girls.
http://en.wikipedia.org/wiki/Sex-selective_abortion_and_infanticide
Sex-selective abortion has been seen as worsening the sex ratio in India, affecting gender issues related to sex compositions of Indian households. According to the 2001 census, the sex-ratio in India is 107.8 males per 100 females, up from 105.8 males per 100 females in 1991.
It is possible that sex-selective abortions have caused an increase in the imbalances between sex ratios of various Asian countries. Studies have estimated that prenatal sex selection has increased the ratio of males to females from the natural average of 105-106 males per 100 females to 113 males per 100 females in both South Korea and China, 110 males per 100 females in Taiwan and 107 males per 100 females among Chinese populations living in Singapore and parts of Malaysia.

According the the U.S. Central Intelligence Agency there are 3,323,608,139 men & 3,278,616,036 women in the world as of July 2007.
The only age group that has more women than men are those who are over the age of 65.
at birth: 1.07 male(s)/female
under 15 years: 1.07 male(s)/female
15-64 years: 1.02 male(s)/female
65 years and over: 0.79 male(s)/female
total population: 1.01 male(s)/female (2009 est.)

I had also heard that woman outlive man most of the time so that could be the reason as well.
The title of this thread should be fixed if people are actually going to believe it's true. 3 to 1 ratio awehawe
