Eight pairs of genes determine IQ (like eight pairs) are all located above the X chromosome, men and women in this first review how the past is
:
male ###### chromosome is XY,
【 】 vying training presentation style and more hot poetry Qinyun, X (eggs ) is from the mother,

female ###### chromosome is XX, X (eggs) from the mother, X (sperm) from the father.
it a boy or girls are made up his mind, do not blame the mother's belly does not live up to expectations !!!!
Please note:
boys are XY,
christian louboutin sparkly shoes, so the boys are all intelligence the genetic from the mother and girls are XX, so the girl's IQ is
one half of father and mother.
because intelligence is the father, mother, girls are affected, so there will be and in effect. Therefore, the distribution of IQ will
girls showing natural distribution (normal distribution), is among the most, on both sides less.
boys because it is completely affected only by the party, so boys will be rendered in favor of IQ distribution in the two extremes. Is
said boys are more gifted in, but at the same time, fool among the boys is particularly high.
from which we conclude that: you do not want to judge a clever clever boy, watching his mother to know.

puma california sneakers I recommend Hot Beijing,
tory burch thora sale, we use the probability to count:
started slightly the calculation of the real classic. . .
the probability of a boy = 1 / 2; the probability of a girl = 1 / 2.
when a boy, his mother's influence for boys IQ = 1
girl, my mother for the girls, the influence of IQ = 1 / 2
So IQ of the mother with his father's influence for the next generation (expected c) ratio is
1 * 1 / 2 + 1 / 2 * 1 / 2: 0 * 1 / 2 + 1 / 2 * 1 / 2
= 0.75: 0.25
= 3: 1
= parent: the parent
