What are the possible genotypes of the parents of a child with Rett Syndrome?
i really dont know. the parents can be normal even if the child has rett syndrome. rett syndrome is caused by a mutation.
Down syndrome is a somatic disorder that results in an additional chromosome 21 in the conceptus (embryo). The resulting child is 2N+1 or 47 chromosomes. The parents are generally 2N. Down Syndrome parents generally have normal 2N children.
Fragile X syndrom is not caused by a classical Mendelian mechanism. It is caused by repeated regions of DNA on the X chromosome. With the information given in the question and the possibility for a new mutation to have been generated in this generation all genotypes are possible. The gender of the affected child and state of health of the parents would help narrow down the possibilities.
Is it possible for 2 parents with down syndrome to produce a child with no non-disjunction disorder please explain why?
Since Down Syndrome is not genetic and is a trisomy, dominant and recessive genes do not play a role and it is possible for two down syndrome parents to have a child without down syndrome.
Both parents have AO genotypes.
Yes, it is quite possible. It does require both parents to have AO(+-) genotypes, which is somewhat rare, however.
Yes, it is possible but it is very unlikely. If you had two parents with Down Syndrome, you would have an 80% chance that your child would have Down Syndrome. [In the UK, Down Syndrome is known as Down's Syndrome.]
Is it possible for 2 parents with down syndrome to produce a child with no non-disjunction disorder please explain?
No, it is possible for 2 parents with down syndrome to produce a child with no non-disjunction disorder because of a gamete is produced with an extra copy of the chromosomes.
the parents could be IAIA IAIB IBIB consider A and B as superscript as i dont know how to write it in superscript
Yes, it is possible. Parents who are O positive may have children who are O+ or O-, depending on the parents' genotypes.
The parents of a child who has Down syndrome each have the normal amount of chromosomes. The parents have 46, the child has 47.
Since Down syndrome isn't a sex-linked trait, it won't be passed down from parent to child, and it has nothing to do with the genetics of the previous generations. Getting Down syndrome happens by a "mess up" in reproduction, not from getting it from previous generations.
Yes. It would take too long to explain genotypes and phenotypes, just know that it is possible.
It would be the mother you would be interested in. My optometrist told me that the color blindness gene is carried by the mother.
Yes. Any child can have down syndrome, as long as the parents pass the gene. Luckily, most people don't have it.
No. Parents who have a child with Down syndrome do not have an increased chance in having another child with Down syndrome. Everyone has the same chance of having a child with Down syndrome, 1%.
Yes, it's possible but there are very slim chances. It depends heavily on the genotypes of both parents
A couple has four children and each child has a different ABO blood type What are the blood types and genotypes of the children and the parents?
parents: AB, O children: A,B,O,and AB -sarahhhh(: ------------------------------------------------------------------ actually, parents has to be type A and type B with genotypes IAi and IBi that's the only way for the offspring to have all the possible blood types - kigesui
Why it is possible for two healthy parents to have a child with a disease caused by recessive allele?
Let us assume that a healthy phenotype results from either the HH or Hh genotypes and a diseased phenotype results from the hh genotype. Therefore, if both parents are heterozygotes (Hh), then the possible genotypes for their offspring are HH, Hh, and hh (Draw a Punnett Square to make sure) in a ration of 1:2:1. This means that there is always a 1 in 4 chance that a child produced by two heterozygote parents is… Read More
If the parents had the genotypes AO and BO, then they could have a child with Type O blood (there would be a 25% chance of this occurring).
A couple has four children and eash child has a different ABO blood type What are the genotypes of the children and the parents?
Parents blood types: A and B genotypes: IAi and IBi Children blood types: A, B, O, and AB genotypes: IAi, IBi, Ii, and IAIB (capital A's and B's are superscript)
One word... Genetics
That would mean that the mother is the one with Down syndrome, since men with Down syndrome are sterile. There is a 50% chance that the child will have Down syndrome and 50% chance that child will be born without.
A child is born with attached earlobes but both parents have hanging earlobes. What are the genotypes and phenottypes fot the parents?
lets use "A" Aa and Aa aa
If one parent is AB- and another parent is B-, then the possible bloodtypes of their child is as follows: AB- BB- B- [or BO-] A- [or AO-] There would be an equal chance of any one of these genotypes from occurring.
Depends on the disease- dominant gene or recessive gene- and the genotypes of the parents.
Yes two non-Down syndrome parents can have a Down syndrome child. This is the most common situation, mainly because very few Down syndrome affected people are parents. Few Down Syndrome affected people become parents, partly because of reduced fertility associated with the syndrome, partly because of an increased risk of passing on the syndrome (very roughly from 1 in 800 to 1 in 3), and partly because of societal restrictions. ___________ Also, the parent(s) who… Read More
A woman with type A negative blood who has children with a man with B blood may have a child of any blood type. The possibilities depend on the genotypes of the parents, which aren't given here.
This is dependent on the circumstance as parents with downs syndrome can still raise a child.
There are many reasons teenagers rebel. Middle child syndrome is one of the reasons a teen can rebel against their parents.
What is the blood type of a child born to two parents with the genotypes IAIA and IBIB for blood type?
IAIB? or IBIA? am i supposed to know??
HH and Hh; Hh & Hh;Hh &hh; HH & hh
If a child has blond hair and both of her parents have brown hair what does that tell you about the allele for blond hair?
Both of the parents were heterozygous with the blonde hair allele, which is recessive. When there are two parents that are heterozygous, there is a 25% chance their offspring will get two of the recessive alleles. A punnett square can be useful when determining the different phenotypes and genotypes possible in offspring
it is possible that a wasp can resemble its parents because of genetics. if a child can resemble its parents, it will be possible that a wasp can resemble its parents. it might not be physical but possible it its genetic coding.
Not necessarily. It could result in a O neg baby depending on their genotypes.
It's a 50-50 possible he or she will have a child with Asperger's Syndrome. BOTH need help to function properly.
no because since they both have down syndrome, they will have 100 percent that they will have a down syndrome baby
Down's syndrome by definition is an over representation of chromosome 21. The most common type is trisomy 21, in which case the genotype of the person with Down's syndrome is 3 copies of chromosome 21. This is denoted as: 47, XX, +21 - if a female 47, XY, +21 - if a male Another type is when the extra piece of chromosome 21 attaches to somewhere else, in which case the genotype will still be… Read More
It depends on the genotypes of the parents. Because albinism is a recessive trait, it's possible for a person to carry the genes for it without displaying the trait themself. However, if you don't have a family history of the disorder, you're very unlikely to end up with an albino kid.
O- would be the only possible blood type for the child.
The risk that the parents of a daughter with RS will have a second child with the disorder is less than 1%.
What are the possible genotypes of the parents if the abnormality describe the abnormality for fragile X syndrome?
A/X X/A NIKKI SMITH **** Less than 1% of Fragile X Syndrome cases are a result of deletion, neither parent is a carrier. If a father is the carrier/full mutation, XY, he will pass the mutated gene to all of his daughters, all of his daughters will be carriers. If the mother is the carrier/full mutation, xX, with each pregnancy she has the possiblity of passing on fragile X as a pre-mutation (carriers) or full-Mutation… Read More
Is it possible for a child to be placed back with the parents if the parents rights have been terminated?
If a parents rights have been terminated they cant get they're child back.
A geneticist can diagnose Klinefelter syndrome before your son is born through a fetal cytogenetic analysis.
People are born gay so if the child is gay the parents had nothing to do with it.
Like any other child? Why treat the child any differently because he or she has a disability. That would be discrimination.
parent who has a child with a down syndrome needs to have a very very wide range of understanding and patient to their child. they should be always positive for their children and wont leave it anyhwere because they are sensitive and all they need was a very definite attention and unconditonal love from their parents because they are dependent of their parents who guides them and never leaves them no matter what.
It cannot (unless the parents were homozygous), but it can help predict the odds of having a child with a genetic disorder.
Yes but the reverse is not possible for two parents with type O to have a type B child
If you have a brother or a sister with Down syndrome does this increase the chances of giving birth to a child with Down syndrome?
no if the one of the parents have it and it is genetic then yes. but in this case no because it is not genetic
