What part of a chromosome carries information and controls a trait?
genei think its in the genetic code that comes from the order the bases are in on a strand of DNA the DNA is in a gene witch is in a chromosome
Which parent is responsible for the genetic error in Turner syndrome?
A Greek study from 1999 reported that the intact X-chromosome was as likely to come from the mother as from the father. This means that there is no parental pattern of responsibility for the missing or defective X-chromosome.
At the beginning of cell division DNA and the proteins associated with the DNA coil into a structure called an?
chromosome.
Doubled rod of condensed chromatin?

The Y chromosome is larger and carries fewer genes than the X chromosome?
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.
A segment of chromosome responsible for a particular characteristic?
DNA or genens these are the segments of the chromosome.
What are chromosome responsible for?
Life man yeah dude
For what are genes on the y chromosome responsible?
For the development of male offspring.
What chromosome is Spina Bifida located on?
There has not yet been a specific chromosome identified as the one responsible for causing spina bifida.
A protein structure that is responsible for moving the chromosome along the microtubule?
kinetochore
What genes are responsible for neuronal migration disorders?
The most well characterized genes include DCX on the X chromosome, responsible for double cortex syndrome, and LIS1 on chromosome 17, the first gene identified for lissencephaly.
Are gentic defects associated with abnormalities of autosomes or of sex chromosomes explain?
genetic defects are responsible for disorders can be on any chromosome wether it is and autosome or a sex chromosome.
What chromosome is affected in fabry disease?
The allele that is responsible of Fabry Disorder/Disease is located on the X chromosome and is the only lipid storage disorder identified as being sex linked.
How many chromosome 7 s are there in the human nucleus?
Two, one from each parent. Over 90,000 genes are found on each chromosome and are mostly responsible for protein productions.
What chromosome mutation causes epilepsy?
You should search up the info on these chromosomes: chromosome 1 chromosome 14 chromosome 21 there is also other genes: presenilin 1 (PS1 or PSEN1) presenilin 2 (PS2 or PSEN2) amyloid precursor protein (APP)
How can duplication of a chromosome of the first pair produce a double head and at the same time affect the wing pigmentation and body organism?
There are multiple genes encoded by this chromosome. The duplication of the chromosome might have dysregulated multiple genes that affect the patterning of the head and body and affect wing pigmentation. On the other hand, one gene might be involved in all these processes. For instance, patients with Down syndrome have three copies of chromosome 21, resulting in developmental issues but also an early onset of Alzheimers Disease.
Why does having only a single X chromosome make a person of necessity female?
Its not a guarantee, but generally it holds true. There are some instances when the part of the y chromosome which determines sex is tacked onto an X chromosome. This can result in XX males. In general though the Y chromosome is responsible for making a biological male.
