The ovum contains 22 autosomes and one X chromosome. Therefore, the mothers contribution is the X chromosome.
Klinefelter Syndrome is neither recessive or dominant. It is a chormosome disorder, and is thus not passed down from generation to generation. The disorder is a random even that occurs.
Y chromosome is autosomal dominant chromosome. When it is present, the sex of the child is male. When both the chromosomes are X, then the sex of the child is female. X chomosome is called as autosomal recessive chromosome.
The alleles on the sex chromosomes are still dominant or recessive, the difference is that even a recessive trait on the X chromosome can be expressed if it is located at a gene locus that has no matching locus on the Y chromosome. The alleles for red-green color blindness are located on the X chromosome is a place that has no corresponding locus on the Y chromosome. Inheritance for a male child depends on the mother's genetics and, if she is a carrier, the male child has a 50% chance of being color blind.
Huntingdons chorea is caused by a dominant allele.
your a**
An allele on either X or Y could be dominant over the allele on the other chromosome, but it is more common for the allele on the X to be dominant, because the Y chromosome is much smaller than the X and contains fewer genes. In many cases, there is no allele for a particular gene on the Y chromosome; so whatever allele is on the Y will be dominant.
Dominant
Down syndrome is neither caused by dominant or recessive chromosomes it is simply caused by an error in the translation process of chromosome 21.
The ovum contains 22 autosomes and one X chromosome. Therefore, the mothers contribution is the X chromosome.

Klinefelter Syndrome is neither recessive or dominant. It is a chormosome disorder, and is thus not passed down from generation to generation. The disorder is a random even that occurs.
nondisjunction
Down syndrome is neither dominant nor recessive. Actually, it is considered to be an "autosomal" trait. This occurs when there is damage to the chromosome.
WOW!! That guy is amazing. A chicken? Histerical, Neurofibromatosis affects only chromosome number 23. It also will affect the brain and is an autosomal dominant genetic disorder.It is when your chromosome has a chicken.
