A child has sickle-cell disease (ss) but neither parent is ill. What must be true of her parents and rsquo genotypes?
The parents are both recessive (Ss) for sickle cell anemia.
What else can I help you with?
A child has sickle-cell disease (ss) but neither parent is ill What must be true of her parents genotypes?
The parents are both recessive (Ss) for sickle cell anemia.
If a child has sickle-cell disease (ss) but neither parent is ill. What must be true of he parents' genotypes?
The parents are both recessive (Ss) for sickle cell anemia.
Hemophilia is a sex-linked recessive disorder. Mary does not have the disease, but both of her brothers do. Neither of her parents have the disease. What are Mary's parent's genotypes (* indicates presence of the hemophilia allele)?
X*X and XY
What are the chances a child will be born with a hereditary disorder or disease?
Depends on the disease- dominant gene or recessive gene- and the genotypes of the parents.
How many genotypes do you receive from your parents?
People receive a total of 46 genotypes from their parents.
What are the genotypes of two parents that pass on the klinefelter's syndrome?
The parents have normal genotypes, because Klinefelter's syndrome is not inherited.
How are the genotype and phenotype of parents related to the genotype and phenotypes of offsprings?
The parents can pass on only the alleles of their genotypes to their offspring. Therefore, the offspring genotypes and phenotypes are dependent solely upon the alleles inherited from the parents.
What is the probability that an individual has one parent with huntington disease will also have Huntington disease?
25% will have the disease if both parents carry the gene. 50% will be carriers. 25% will be neither.
Can a person be a carrier for a genetic disease if neither or only one of their parents are carriers?
Yes, it is possible for a person to be a carrier for a genetic disease even if neither of their parents are carriers. This can occur if the person has a new mutation in the gene associated with the disease. Carriers have one copy of the mutated gene, which they can pass on to their children.
What is a punnett square used to predict?
A Punnett square is used to lay out the possible genotypes of offspring based on the genotypes of the parents being bred. From this, the probabilities of certain phenotypes and genotypes can be determined.
What percentage of possibles types of offspring had the same genotype as the parents?
That depends entirely on the genotypes of the parents.
What percentage of the possible types of offsprings had the same genotype as the parents?
That depends entirely on the genotypes of the parents.
