What is the best blood group and genotype?
If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO. A blood test of either type AB or type O is more informative.
In terms of compatibility, someone with AA genotype can marry anybody. It is safe for someone with AS to marry someone with AA genotype. Two sickle cells should not even have a relationship or get married. Individuals with the AA genotype should help you prevent genetic abnormalities by marrying the AS, AC, and SS.
- As you can see, only one out of the eight boxes is OO -/-. That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type. Each of their kids will also have a 3 in 8 chance of having A+, a 3 in 8 chance of being O+, and a 1 in 8 chance for being A-.
- What are the major blood types?
If your blood type is: You can give to: You can receive from: O Positive O+, A+, B+, AB+ O+, O- A Positive A+, AB+ A+, A-, O+, O- B Positive B+, AB+ B+, B-, O+, O- AB Positive AB+ Only All blood types
- When two of the same alleles for a gene are present, the genotype is said to be homozygous e.g. BB or bb. But if different alleles are present for the same gene, e.g.. Bb, then they are said to be heterozygous.
There's no hope of having a child with the genotype AA. But there's no danger either. Someone with the genotype AS should only marry someone with the genotype AA because if AS marries AS there's one out of 4 chances (AS, AS, AA and SS) that they will have a child with the sickle cell disease.
- "Actionable" is defined here to mean that some action can be taken by the individual and/or her physician to prevent a genetic-related disease or disorder from occurring, or to alter in some way its natural progression.
- If a person does not inherit the defective gene from the affected parent they can't pass it on to their own children. Huntington's Disease does not appear in one generation, skip the next, then reappear in a third or subsequent generation. However it may appear to skip a generation.
- There is no treatment to stop or reverse Huntington's disease, however there are some medications that can help keep symptoms under control. Treatment for HD includes the drug tetrabenazine, antipsychotic drugs, antidepressants, and tranquilizers. Patients who exercise tend to do better than those who do not.
Genotype and phenotype are very similar-sounding words that are related, but actually mean different things. The genotype is the set of genes in our DNA which is responsible for a particular trait. The phenotype is the physical expression, or characteristics, of that trait.
- Genotypes and phenotypes. Considering the alleles of a gene present in an organism and the physical results, brings us to the terms genotype, phenotype, and trait. An organism's genotype is its specific combination of alleles for a given gene. A trait is the general aspect of physiology being shown in the phenotype.
- genotype. In a broad sense, the term "genotype" refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes. Each pair of alleles represents the genotype of a specific gene. For example, in sweet pea plants, the gene for flower color has two alleles.
- The two copies, called alleles, can be slightly different from each other. For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent. An individual with one dominant and one recessive allele for a gene will have the dominant phenotype.
