The other chromosome pairs, called the autosomes, appear to be identical twins; they are superficially indistinguishable. In contrast, the X and Y chromosomes appear to be vastly different from one another.” ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!

This is a video from the free online course Genealogy: Researching Your Family Tree from University of Strathclyde, available on FutureLearn.com: https://www.futurelearn.com/courses/genealogy/ An interesting look at how the Y chromosome is passed on to males through the different generations, much like a surname is passed down.

X chromosome from dad will result in a girl, Y chromosome from dad will give a boy. Both are of equal value, to be loved and treasured.
Can you influence the gender of your future baby at conception? What can you do to conceive a boy or a girl? If you want to choose the gender of your baby – watch this video. The calculations are quite easy, while chances to conceive whatever sex you want – a boy or a girl – increase dramatically. Of course, you can rely on the Lord or a bit of luck. But if through simple calculations and actions you can to choose the gender of your baby – a boy or a girl – why not do this? It turns out that things like pregnancy planning, a conception calendar or an ovulation calculator are so elementary, you can come to grips with them in just five minutes. And then all you have to do is calculate the right timing for the desired gender. Who would you like – a boy or a girl?
The video explain about XX and XY chromosome which determines the gender and effect of hormones in determining gender.

View full lesson: http://ed.ted.com/lessons/secrets-of-the-x-chromosome-robin-ball The sequence of DNA that we inherit from our parents encodes directions for making our cells and giving us specific traits. Identical twins have the same DNA sequence, so how can one twin end up with a genetic disorder while the other twin does not? Robin Ball explains how the secret lies in X chromosome inactivation. Lesson by Robin Ball, animation by Anton Trofimov.
Epigenetics means women have different active x-chromosomes in different cells.

At this point the x-chromosome from Mom and the one from Dad are both active. But in order for proper development to occur, one of the x chromosomes must be switched off. Through a tiny molecular battle within each cell, one of the x-chromosomes wins and remains active while the loser is deactivated. This is done by wrapping the DNA tighter around proteins, modifying histone tails, and DNA methylation - molecular markers to indicate this DNA should not be read. What's surprising is that it's pretty random which x chromosome wins - sometimes it's Mom's and sometimes it's Dad's. So when a female is just 100 cells big, her cells have a mix of active x-chromosomes, some from Mom and some from Dad.
What happens when your child is dealt a biological hand that doesn't fit neatly into "male" or female?" As many as 1 in 2,000 children are born with some Intersex trait. If it's so common, why is it so unheard of? Hann Lindahl PechaKucha Night Champaign-Urbana Vol. 17
