1.. they only inherit the X chromosome
Male is XY , female is XX .
the genes they carry.
In humans, each sex gives exactly 23 chromosomes. The X chromosome, coming from females, has more base pairs that the Y Chromosome, coming from males. So in terms of DNA, females provide more base pairs that males do.
To acquire something by bequest means to inherit it according to the terms of a will.

Downs syndrome is a genetic abnormality caused by an extra chromosome, in simple terms - as a healthy individual you inherit 22 chromosomes from your mother and 22 from your father, so that's 44 altogether, 1 chromosome from each of your parents will combine to form 22 sets, in a person with Downs syndrome there is an extra abnormally shaped set of chromosomes. So in short a person with Downs syndrome has 23 chromosomes instead of 22.
Sperm cell, as it's haploid (23 chromosomes) as opposed to diploid (46 chromosomes).
This is speaking in terms of MITOSIS.A typical human cell has 46 chromosomes. Each offspring cell receives anidentical copy of the original cell's chromosomes. So the two daughter cells will have 46 chromosomes each as well.

Chromosomes are strands of DNA, sections of which constitute genes. In other words, genes are tiny, chromosomes are very large.
By taking the DNA of the embryo, putting it through some tests and coming out with results on whether it's a female (XX chromosomes) or a male (XY chromosomes). These chromosomes are the same in terms of sex selection for all mammals.
