For sickle-cell disease assume S is the dominant allele and s the recessive allele Which genotypes are possible for offspring of a carrier (Ss) and a person who lacks the sickle-cell allele (SS)?
SS,Ss
Can a person who has been successfully treated for sickle cell disease still transmit the disease-causing allele to offspring?
Sickle-cell anemia can only be transmitted if both partners have the disease.
Which person is most likely to develop symptoms of the disease that is tracked in the pedigree?
i need to see the pedigree...
A person can be tested for the allele that causes Tay-Sachs disease because the what of that allele is different from that of the normal allele?
DNA sequencing
What type of allele causes huntington disease?
The allele that causes Huntington's disease is dominant. This means that there only needs to be one present in the gene for it to show in the person's phenotype.
Which genotypes are possible for offspring of a carrier (Ss) and a person who lacks the sickle-cell allele (SS)?
SS,Ss
How many copies of the faulty allele are needed for the person to have Is Huntington's disease?
40 or more.
A person can be tested for the allele that causes huntingtons disease because of that allele is different from that of a normal allele?
Because Huntington's is a genetic disorder and it is known what sequence in what region causes the disorder.
Can a person with Sickle Cell Disease pass it to their offspring?
Yes, it is an inherited disorder.
What is a person who has one recessive allele for a trait and one dominant allele for the same trait and is able to pass in the trait on to their offspring?
That is heterozygous. Some scientist call these "hybrids"(no joke)The person is heterozygous for that trait and will have the dominant phenotype.An organism with both a dominant and recessive allele for a specific trait is called an heterozygote. They are heterozygous for this trait.
Is huntington's disease determined by multiple alleles?
No. This is a single gene disorder. If at least one allele has the huntington's mutation, the person will eventually develop the disease.
What happens to the recessive allele in a heterozygous offspring?
The recessive allele is present, but not shown in complete dominance. This is because the dominant allele is completely dominant over the recessive allele, therefore it is shown, while the recessive allele is hidden.
