Is the baby guaranteed to be free from genetic disorders if the chromosome configuration appears normal?
If you are pregnant there are many thoughts running through your mind including the potential health of your unborn baby. There is no guarantee the baby will be free if the genetic testing comes back clear, however, there is a good chance all will be well. If you have any concerns, talk to your doctor.
What else can I help you with?
When a chromosome appears by itself within a karyotype and not as a pair it is known as?
monosomy. This term refers to the condition where an individual is missing one copy of a particular chromosome and only has one copy instead of the normal two.
What is an inherited disorder that appears more often in males than females?
Color blindness is an inherited disorder that appears more often in males than females. The most common form is red-green color blindness, which is due to a mutation on the X chromosome that is more likely to affect males since they have only one X chromosome.
Are Barr body projection of extra chromatin on the an X chromosome?
Yes, a Barr body is an inactivated X chromosome seen in the nuclei of female mammals. It appears as a small, dense, dark-staining body due to the condensation of the chromatin, which is a result of X chromosome inactivation to equalize gene expression between males and females.
In examining a population of fruit flies you notice that a certain trait appears much more often in males than in females how can you explain this?
This trait is likely located on the sex chromosomes, as males have one X chromosome and one Y chromosome, while females have two X chromosomes. Therefore, if the trait is located on the X chromosome, it will be more common in males because they only need one copy of the gene for it to be expressed.
How many chromosomes would a cell have in prophase in a human?
In human cells, during prophase of mitosis, there are 46 chromosomes, which consist of 23 pairs. Each chromosome is duplicated and appears as two sister chromatids joined at the centromere. Therefore, while there are 46 individual chromosomes, they are organized as 92 chromatids.
Most sex-linked genes are found on which chromosome x y?
Many sex-linked genes are found on the X chromosome. More than 100 sex-linked genetic disorders have now been mapped to the X chromosome. The human Y chromosome is much smaller than the X chromosome and appears to contain only few genes.
What is the function of the B4 Chromosome?
It appears that on the B4, there is a gene that reinforces nicotine dependence.
What is the genetic cause of Down syndrome?
Both syndrome's indicate the presence of a 47th chromosome (or extra part of a chromosome). Most humans have 23 pairs of chromosomes, totaling 46 chromosomes. For Down's syndrome, the 47th chromosome appears with the 21st pairing. For Klinefelter's syndrome the 47th chromosome appears with the 26th pairing (the gender chromosomes.)
Why has the category of psychophysiological disorders been dropped from the DSM?
It appears that all diseases have psychological components
Cannot complete install program configuration?
There appears to be a configuration error. You have associated Konqueror with application/x-msdos-program, but it cannot handle this file type.
What does it mean a trait is said to be sex-linked?
Generally the trait is on the X chromosome, as the Y is rather small and full of deleterious mutations and has few working genes. But and trait that is located on a sex chromosome is said to be sex linked. Naturally, women have two, XX, chromosomes, so ore protected statistically from many sex linked recessive disorders.
When a chromosome appears by itself within a karyotype and not as a pair it is known as?
monosomy. This term refers to the condition where an individual is missing one copy of a particular chromosome and only has one copy instead of the normal two.
How do pigmentation disorders affect skin colour?
Pigmentation disorders can cause the skin to be darker or lighter than normal. They may also cause spots or skin that appears to have smooth white patches.
What screen appears by default when the windows server 2008 operating system is first installed?

What is an inherited disorder that appears more often in males than females?
Color blindness is an inherited disorder that appears more often in males than females. The most common form is red-green color blindness, which is due to a mutation on the X chromosome that is more likely to affect males since they have only one X chromosome.
What is the prognosis for a patient with factitious disorders?
Some patients have only one or two episodes of factitious disorders; others develop a chronic form that may be lifelong. Successful treatment of the chronic form appears to be rare.
