Question 1

what is haploidization?

Accepted Answer

1/2 chromosomes: Haploid is half a set of chromosomes. The egg and the sperm each give half of the complement of chromosomes to the embryo.

Question 2

has haploidization been done?

Accepted Answer

Future science: This was intended to allow a woman or a man unable to produce sperm to fertilize an egg and bring a child into the world. It has not been successful clinically so far. I hope that at some time, you are able to get what you want.

Question 3

is xyy syndrome-                                 
sex-linked-yes or no; particular chromosome; recessive or dominant?

Accepted Answer

Klinefelter Syndrome: Hi,

Klinefelter Syndrome, or XYY syndrome is a syndrome where males have an extra Y chromosome, which makes them 47 XYY rather than 46 XY.

It is not a sex-linked, autosomal dominant, nor autosomal recessive disorder.

The inclusion of the extra Y chromosome is thought to be a random event, even in cases of 47 XYY mosaicism.

Question 4

which chromosomal mutation occurs in alagille syndrome?

Accepted Answer

Alagille Syndrome is: Caused by an autisomal dominant mutation in the jagged-1 gene on the short arm of chromosome 20, 20p12. Because of "variable penetrance" some parents don't have noticeable symptoms,  especially if they have mosaicism, i.e., some, but not all, of their cells carry the mutation. Therefore, although 15% of cases are "sporadic, " i.e., from new mutations, it is recommended that parents be tested.

Question 5

what chromosome is mutated in sickle cell disease?

Accepted Answer

11: The beta globin gene is mutated in sickle cell anemia; it is located on chromosome 11.

Question 6

what is bardet biedl syndrome?

Accepted Answer

Bardet-Biedl: Bardet-biedl syndrome is a disorder that affects many parts of the body. The signs and symptoms of this condition vary among affected individuals, even among members of the same family. There can be: vision loss, obesity, extra fingers, delayed speech, delayed development of motor skill, dental abnormalities, behavioral problems, and others.

Question 7

is hemophilia a gene mutation?

Accepted Answer

Yes: Both hemophilia a and b are due to mutations in genes on the x chromosome.

Question 8

does the asperger syndrome have xyy chromosome?

Accepted Answer

Asperger's disorder: There is no consistent chromosomal abnormality associated with asperger's disorder, either for males or females.

Question 9

what is a hereditary hemochromatosis dna mutation?

Accepted Answer

Gene Mutation: This is a mutation in one of the genes that help to process iron absorption.  The mutation, if present in 2 copies, can cause too much iron to be absorbed.  The excess iron then deposits in other organs and can cause disease - cirrhosis, diabetes, impotence.  Having only one mutation may not lead to disease.  You should discuss this with your doctor to see if you are at risk of developing disease.

Question 10

hows patau syndrome inherited?

Accepted Answer

Not inherited: Patau syndrome, or trisomy 13, is not inherited, in that a baby does not "get it" from either parent.  It is usually caused when the egg does not divide properly at the time of fertilization.  This accident causes a baby to get an extra number 13 chromosome in every one of its cells.  Trisomy 13 is rare, but a very serious condition.  Most babies with it die before birth or shortly after birth.
