What is the most significant aspect of a dominant genetic disease?
You cannot be a carrier of the disease, Either you have it, and offspring can inherit it, or you don't- and it stops there.
Are rabbits born de-formed if they mate with their mothers?
Mating with a mother or close relative does not always result in abnormal offspring, but it DOES increase the chances that offspring may be born abnormal. Cells contain genetic materiel 1/2 of which comes from the father and 1/2 from the mother. This means that all genetic material, apart from that of the sexual genetic material, is pared and any faults in one set are usually corrected by the (good) set form the other parent. When close family members reproduce the chances of getting a pair of faulty genetic sets increases and abnormal offspring become more likely, especially if this inbreeding continues for generations.
When sex cells randomly combine during fertilization to produce offspring there is?
increase genetic diversity
Is it true carriers of genetic diseases who do not have the disease themselves have recessive genes for the disorder?
Yes. They can pass it on to their offspring.
What can you do to prevent your chances of getting sickle cell disease?
Sickle cell can not be "caught". It is an inherited genetic disease and is only in the African American community.
Does sexual reprouction increase or decrease genetic diversity?
Sexual reproduction increases genetic diversity, because the offspring will not be genetically identical to either parent, being a genetic blend of the two parents.
Could a parent with Down syndrome give their offspring Down syndrome?
As the disease is genetic, DS women have nearly a 50% chance of passing on DS to their offspring if the father does not have DS.
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
Can mix race offspring cause genetic mutation which lead to viruses such as HIV?
No, HIV is a communicable disease caused by a virus, not by genetics.
. Is a person who is homozygous recessive for a recessive genetic disease a carrier?
No, because he or she cannot pass the gene on to his or her offspring (because he or she does not have a copy of the gene).
Are all Genetic disorders are inherited disorders?
If it is a genetic disease/disorder that means it is a problem in the person's DNA which was created before the birth therefore it is not acquired. Although it can be inherited, it can also have no relation to the family of the offspring whatsoever.
A carrier of a genetic disorder who does not show symptoms is most likely to be to transmit it to offspring?
A carrier of a genetic disorder who does not show symptoms is most likely to be heterozygous for the trait and able to transmit it to his offspring. The term heterozygous refers to a pair of gene with one dominant trait and one recessive trait.
