The phenotype of the rr genotype would be?
The genotypes would be: RR, RR, RR, and Rr As for the phenotypes, you cannot tell without knowing what the alleles represent.
Can you determine a persons genotype based on phenotype?
In some cases but not others. Certain alleles can be dominant, which means that they will dictate the phenotype should there be a clash of alleles in the genotype. Other alleles can be recessive, which means you'd need both of these alleles in these genotype in order for it to dictate the phenotype. This means that if a person's phenotype represents a dominant trait, we cannot be certain what their genotype is. If, however, it represents a recessive trait, we know that their genotype must be the recessive allele twice.
Why is it difficult to determine the genotype of an organism that has a dominant phenotype?
NO, because a dominant phenotype could either be homozygous or a heterozygous.so unless you are sure about the genotype of parents we can't determine it...but we can determine the genotype of a person showing reccessive phenotype, as a recessive trait always expresses itself in a homozygous condition...
Which term refers to the genetic makeup of an organism?
The genetic makeup of an organism refers to the set of genes responsible for a particular trait. The genetic makeup of an organism is also referred to as the genotype. Genetic makeup of an organism decides the phenotype or expression of information within the genes. Examples of genetic makeup of an organism - gene responsible for eye color gene responsible for hair color gene responsible for how your voice sounds gene responsible for a bird's beak Difference between the genotype and phenotype of an organism Genotype refers to the set of genes that has the information for a particular trait whereas the phenotype is the physical expression of that particular trait.
If a heterozygous male mates with an albino female what percentage of children will be albino?
Albinism is a sex-linked trait. Accordingly, the description of "heterozygous male" doesn't make sense. The sex chromosomes for males are XY, and usually genetic disorders are passed down by the X chromosome (which is the case for albinism). So in the problem, we aren't sure whether the male is XaY or XAY. It would be more helpful to know if the male was albino or not; we would then immediately know his genotype. We can, however, figure out the genotype of the female. Because albinism is recessive, we can deduce that her genotyple is XaXa. But without knowing the male's genotype or phenotype, the offspring percentages cannot be calculated.
What are the characteristics of phenotype?
A phenotype is the physical characteristics of an organism. It is determined by the genotype, so the characteristics are endless. You have to specifically know the genotype or the physical features to determine the phenotype
What is a genotype and phenotype middle school level?
All I think you would need to know at this point is that the genotype is the genetic makeup or background of an organism and the phenotype is what the organism looks like physically. An easy way to remember this is that the genotype is the genes.
What is a phenotype of a chicken with the genotype Fb Fw?
Since the mom/dad has (for example) white feathers and the other with black feathers. The genotype is FB FW (as we know) so because of codominance the phenotype would also be FB FW (:
John's father has genotype BO and his mother has phenotype O What are the chances of John being phenotype B?
50%. First you need to remember that a BO genotype would result in a B phenotype. The only way to have an O phenotype is to have an OO genotype. Therefore, we know that John's parents are BO and OO. Then, you can make a Punnett square. B O O BO OO O BO OO Half of the offspring between John's parents would have genotype BO and half would have OO. Therefore, half would have each of the phenotypes B and O. The answer is 50%.
Is it possible to know genotype of unborn babies?
Yes, is possible 2 know genotype of unborn babies
The phenotype of the rr genotype would be?
The genotypes would be: RR, RR, RR, and Rr As for the phenotypes, you cannot tell without knowing what the alleles represent.
What is the phenotype of an orgarism?
The phenotype is the characteristic or trait that is expressed in the organism. So, for example, if a person has blue eyes, his/her phenotype for eye color is blue. In case you didn't know, the genotype is simply the gene that codes for the phenotype. So with the blue eyes, the genotype of the person for eye color must have been recessive alleles (because blue eyes are a recessive trait).
Can you determine a persons genotype based on phenotype?
In some cases but not others. Certain alleles can be dominant, which means that they will dictate the phenotype should there be a clash of alleles in the genotype. Other alleles can be recessive, which means you'd need both of these alleles in these genotype in order for it to dictate the phenotype. This means that if a person's phenotype represents a dominant trait, we cannot be certain what their genotype is. If, however, it represents a recessive trait, we know that their genotype must be the recessive allele twice.
Why is phenotype more important than genotype?
Phenotype is the displayed characteristics of the organism, as opposed to the genotype, which is the gene sequence of the organism. Phenotype is important because it includes everything that the organism can do. Whether a plant is pink or red, an example of phenotype, can influence whether or not a bee will be attracted and pollenate it. The presence of cystic fibrosis, a debilitating disorder in humans, is caused by genotype but expressed through phenotype, and can be the difference between death at twenty or a long life to eighty.
How do you know your baby's genotype in the womb?
It is possible to know about your baby's genotype in the womb. If one has a great deal of money, they can pay a doctor to do special testing on the fetus.
What are organisms with the genotype tt is also know as?
two capital or two lowercase letters in the GENOTYPE (ex: TT or tt) it's also called HOMOZYGOUS.
Son is O positive and mommy is A positive what is the dad?
no Yes. If the mother's phenotype is A, the mother's genotype may be AA or AO. If the mother's phenotype is A, the mother's genotype may be AA or AO. If both are AO, the baby may inherit O from both parents, and the baby's genotype will be OO, and the phenotype will be O. A baby born to two parents who are genotype AO can have the following genotypes: AA, AO, OO. The possible phenotypes are therefore A or O.
