What else can I help you with?
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?
The DNA sequence of the allele that causes Tay-Sachs disease is different from that of the normal allele. This difference in the DNA sequence allows for specific genetic tests to be conducted to identify the presence of the Tay-Sachs disease allele in individuals.
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.
What is it called when you have only one dominant allele to get the disease?
if an indivigual has a dominent allele for a disease he/she is an affected individual.
What is a person who has a dominant and one recessive copy of a disease gene?
A person who has one dominant and one recessive copy of a disease gene is typically considered to be affected by the condition if the disease is caused by the dominant allele. In this case, the dominant allele's effects will manifest, overshadowing the recessive allele. The individual may not express traits associated with the recessive allele, as the dominant trait takes precedence.
How many copies of the faulty allele are needed for the person to have Is Huntington's disease?
40 or more.
Which genotypes are possible for offspring of a carrier (Ss) and a person who lacks the sickle-cell allele (SS)?
SS,Ss
What happens to the recessive allele in a heterozygous offspring?
In a heterozygous offspring, the recessive allele is present, but it is overridden by the dominant allele in terms of physical expression. The recessive allele still remains in the genetic makeup of the offspring and can be passed on to future generations.
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.
