XX are the sex defining chromosomes for a girl and XY for boys
i think it isxyxx xx xyxx xy
XX or XY are the combination of geanes for reproduction process in humen being. Whereas XX is the genetic representation of a female and XY being of a male. The genes XX & XY appear in the 23rd pair of chromosomes in the karyotype of a human.
xx and xy genetic mutation.
Two (XX or XY) with the exception of genetic abnormalities.
xx is girlxy is boy
XX are the female chromosomes and XY are the male chromosomes.
XX and XY is the male-female cross in humans and some other organisms. XX= female, XY= male.
Men are XY.
XX = Female, XY = Male :)
a males gines are xy and females gines are xx. and there is no yy gines
Females are XY.
In humans, gender is determined by the x and y chromosomes, with xx being a genetic female and xy being a genetic male
Females have xx chromosomes, males have xy.
It is referring to the male chromosome whereas the the female gender chromosome is XX.
Yes, but unlike with mammals, in the case of birds females have XY, and males have XX. With mammals like us males have XY and females have XX.
Females' eggs always provide an X. If the sperm is X, the child is female (XX); if it is Y, the child is male (XY).
XX means female XY is male
XY is a male while XX is female.
The female has xx and the male has either xx or xy
Sperm is X or Y, it fertilizes the egg forming XY or XX. XY would be male and XX female.
Because in males they have only 1 X chromosome. The other one is Y. But in females they have 2 XX chromosomes so the chance that X chromosome will carry disease to cause illness is lower. Example: lets say xx (recesssive) phenotype makes illness, whereas XX (dominant) is healthy. A woman can have XX, Xx, xx right? Since Xx is a carrier and XX is healthy you wont see the illness. only xx can make illness. 1/3 chances she is sick. However in males they have XY. so he can only have either XY or xY. No carrier form is present. The chances he will be sick is %50. got it? Im a genetic engineer and molecular biolog so count on me :)
The mother has chromosomes XX and the father has the chromosomes XY
