Genotype codes for phenotype. Phenotype is the expressed trait, for example, black fur. The genome that codes for black fur would be BB for example

When can you accurately determine a person's genotype from their phenotype?
Yes you can accurately determine an organisms genotype by observing it's phenotype, however some phenotypic traits resulting from homozygous or heterozygous combinations of alleles, may make the prediction impossible.
How does genotype affect phenotypes?
They are related to each other because...Genes and alleles are the traits inside an object, when using a punnet square, we take the genotype out of that object to make experiments.
What are some phenotypes of the kangaroo?
This qurestion makes little sense as the phenotype is the physical expression of the kangaroos genome (or genotype). Thus, any physical feature of the kangaroo is a phenotype of the kangaroo.
Is chromosomal mutation dominant or recessive?
They can be both. Wikipedia provides small descriptions of some of the different types of mutation
What type of blood would you have if parents are o negative and a positive?
There is no single answer to this question.First, some definitions. PHENOTYPE is how the trait is physically displayed in the person, so the parents in this case have the phenotypes O and A. GENOTYPE is the pair of genes that a person carries that determines their phenotype. A RECESSIVE gene is one "trumped" by a DOMINANT gene in the genotype; for blood typing, O is the recessive gene and A and B are dominant. For a person to show the recessive phenotype, they must carry BOTH recessive genes; so, a person with type O must carry two O genes, genotype "OO".OK, now for our situation. The O parent has genotype OO, as explained above, and so can ONLY pass on the O gene. The type A parent, however, can have genotype AA or AO. Because the A gene is dominant, with the AO genotype the parent is still type A but can pass on EITHER the A gene or the O gene. The child can therefore end up with phenotype AO and be type A or OO and be type O. If exactly one-half of people with type A blood have genotype AA and one-half have AO, the probability of this child being type A is 75%.For the Rh factor (positive and negative), positive is the dominant trait and negative is recessive. The A- parent must be genotype -/- and can only pass on the - gene. The O+ parent can be +/+ or +/- and can pass on either gene, same situation as above. Again, if people with Rh type positive are split exactly 50/50 in genotypes, this child has a 75% chance of being positive.
What we call the observable expression of genes present in an organism?
When genes are expressed, the result is called phenotype. What is actually in all the genes (some are recessive) is called the genotype.
When can you accurately determine a person's genotype from their phenotype?
Yes you can accurately determine an organisms genotype by observing it's phenotype, however some phenotypic traits resulting from homozygous or heterozygous combinations of alleles, may make the prediction impossible.
What is the way an organism looks?
Very small. Microscopic, in fact. But with a microscope and some proper staining techniques, they are quite varied in shape and size, for example.
How does genotype affect phenotypes?
They are related to each other because...Genes and alleles are the traits inside an object, when using a punnet square, we take the genotype out of that object to make experiments.
What best describes the factors that affect a phenotype?
The genotype and the environment both affect a phenotype.
Why natural selection acts on the phenotype rather than genotype?
natural selection is a passive prosess . the mechanism of some individuals to be selected more than others is because they fit their environment more. and phenotype shows the fitness .
Can 2 organisms have different genotypes but the same phenotype?
No. It is possible for the reverse to be true, two organisms can have the same phenotype but a different genotype. This is because the phenotype is what you will see on the outside whereas the genotype is the combination of alleles and since this determines the phenotype, two organisms with the same genotype will have the same phenotype. So, basically, no. Actually 2 organisms can certainly have different phenotypes with the same genotype--this refers to the concept of penetrance. Some people can have the gene for a condition but never show symptoms. An excellent example of this is the disease neurofibromatosis. This disease has very variable penetrance in which a child of an affected parent may show no signs of the disease, but then have a child with a severe form.
Can two organisms have different genotypes but the same phenotype?
One way is if an allele for the gene in question is dominant. Homozygotes for the dominant allele and heterozygotes will both have the same phenotype.Organisms have the same phenotype, or physical characteristics. They do not, however, have the same genotype, or genetic makeup. If T represent tall, and t represnts short then the organism will have the genotypes TT and Tt. If you make a Punnett square you will have the same phenotype but different genotypes. Unless some weird mutation occurs....

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.
What are some phenotype non examples?
Cut down a bit of stomach fat every year by being lazy and eating potatoe chips.
Why is genotype not the only factor that affects phenotypes?
Phenotype is the observable characteristics shown by an organism it is affected by both genotype (alleles and genes) and environment. If ,for example, a boy inherited white-colour skin from both his mother and father but he spent a lot of time in the sun then he's skin will get darker. Or if his parents were both tall but he didn't play any sports or he didn't eat healthy food so he didn't receive the nutrients needed to switch on these genes he'll be short.
