What are some chromosomal disorders?
The most common type of chromosomal disorder is the Down syndrome caused by an added copy of chromosomes 21. More common chromosomal disorders are Klinefelter's syndrome and Turnerâ??s syndrome.
Can a person with 45 or 48 chromosomes survive?
Someone with 45 chromosomes can survive if the missing chromosome is a sex chromosome. 48 chromosomes would be 2 trisomies...if one was a trisomy of chromosome 21 and the other trisomy involved one of the sex chromosomes this would probably produce a living offspring. Other trisomies tend to have more negative effects and it is unlikely that multiple trisomic individuals would survive.
Why can't boys get turner syndrome?
In the vast majority of people, they are either male (having one X chromosome and one Y chromosome) or female (having two X chromosomes) in every single cell in their body. In people with Turner's syndrome, however, their cells have only a single X chromosome. For this reason, Turner's syndrome is sometimes referred to as an "X-O" disorder (to differentiate it from the state of being male - XY, or female - XX). Because Turner's syndrome sufferers do not conform to the traditional notions of genetic maleness or femaleness, then, it would be improper to define Turner's as either a male or a female syndrome. Its sufferers are neither. In Addition: There is a form of Turner-like Syndrome which affects a male children; this form is called "Swyer Syndrome." These male children are NOT born with functional gonads (testicles); the gonads are NOT on the outside of the body as normal, they are inside. For all intense purposes, these children appear to be female with abnormally enlarged female genitalia, but this deformity is actually a small penis. So therefore, the sex glands are ambiguous, the penis does NOT appear to be a penis, nor will it ever function normally. So it is usually suggested by their doctors, that these children be raised as "girls." Right or wrong, this is usually done for the child's sake, with the thought that it will make their life's easier in the long run to be raise as a girl, and in many cases it works out.
What is wrong with someone's eyes if they can only see stuff on gray paper?
They have visual retardation syndrome
What is considered aneuploid?
Aneuploidy is a type of chromosomal abnormality characterized by an abnormal number of chromosomes in a cell. This can result from the gain or loss of entire chromosomes or parts of chromosomes, leading to genetic disorders and health problems. Examples include Down syndrome (trisomy 21) and Turner syndrome (monosomy X).
How does nondisjunction cause chromosomal disorders?
Nondisjunction is the disappointment of homologous chromosomes to detach accurately during meiosis. This outcomes in the creation of gametes containing a more noteworthy or lesser chromosomal sum than typical ones. Therefore the individual might create a trisomal or monosomal condition.
Was Nat turner guilty after the rebellion?
Yes, Nat Turner was wrong when he decoded to attack and kill people.

How are karyotypes associated with genetic diseases?
Karyotypes can reveal chromosomal abnormalities associated with genetic diseases, such as Down syndrome or Turner syndrome. By examining the number, size, and structure of chromosomes in a karyotype, geneticists can identify genetic disorders caused by changes in chromosome number or structure. Karyotyping is an important tool in diagnosing and understanding genetic diseases.
Who is the author of the Cartoon Network?
I could be wrong, but my guess is, Ted Turner.
What happens when something goes wrong during meiosis - -?
it can go really weird
What is a punnet square for Down syndrome?
Down Syndrome is not represented by a punnett square because it is not a genetic disorder. Instead, it is a chromosomal disorder. Humans have 23 pairs of chromosomes adding to a total of 46 chromosomes. Individuals who have Down Syndrome have a total of 47 chromosomes because instead of having a set of 2 #21 chromosomes, he/she has 3 #21 chromosomes. This is a result of nondisjunction which can occur during meiosis. During meiosis, the chromosomal number is supposed to be halved. During nondisjunction, all of the homologous chromosomes (matching chromosomes from mom and dad) do not separate during meiosis. In the case of Down Syndrome, the #21 chromosomes fail to separate during meiosis. This results in an egg or sperm cell having one less or one more chromosome #21. If a normal egg or sperm forms a zygote with a egg or sperm that has an extra #21 chromosome, the resulting person will have Down Syndrome, also called Trisomy 21. The same thing can happen for other chromosomes, resulting in a different disorder. This question has been improved by another user: actually, this is both a genetic disorder and a chromosomal disorder. It is a genetic disorder because this disorder is often transmitted from one (or both) of the parents to their young. It is possible to make a punnett square, however there is a better way to do this, which is why you probably will not find a punnett square of this disease online. The better way is by using a karyotype. I know this because i am in a 9th grade bio honors class and i have been studying this disease for over 2 weeks now.. hi yea no your wrong because down syndrome is a genetic disorder :)
