Two alleles A Melanic and a non-melanic control a polymorphism in which the the melanic condition is dominant over the normal What are the genotypes and phenotypes in this polymorphism?
Lewdacris
Genotype: what's in the genes. Phenotype: What shows up.
Melanic: M
Non melanic : n
Genotypes: MM Mn nM nn
Phenotypes is same order: Melanic, Melanic, Melanic, Non-melanic.
(if this is a question above the level of GCSE someone else should answer it!)

Describe how phenotypes can be used to predict genotypes in a pedigree?
When enough phenotypes in a family are known the genotypes can be infered.
Which genotypes have dominant phenotypes?
The genotypes in which one or more alleles is dominant.
Can phenotypes OB produce genotypes As?
No.
Why isn't it possible to have more genotypes than phenotypes?
I think you have the question backwards, "Why isn't it possible to have more phenotypes than genotypes?" There are always more or an equal number of genotypes relative to phenotypes. The phenotype for a simple dominant/recessive interaction (for example) T for tall and t for short where TT is tall, Tt is tall and tt is short has three genotypes and two phenotypes. If T and t are co-dominant then TT would be tall, Tt would be intermediate and tt would be short. (Three phenotypes and three genotypes.)
What genotype is produced by the phenotype B?
Genotypes are not created by phenotypes, they are the alleles/genes of the organism. Genotypes (in combination with environment) produce phenotypes. It would be expected that the genotypes Bb and BB would produce the phenotype B.
Does natural selection act on genotypes?
Indirectly, yes it does. But it can only act on genotypes through their phenotypes.
What polygenic trait can have many possible genotypes and -?
Many possible genotypes, producing ,any possible phenotypes.
AAA AAA what are the possible genotypes and phenotypes os their children?
Possible genotypes would be AA and Aa. Phenotypes cannot be determined here because they are the physical, observable results of a genotype.
Which can you physically see genotypes or phenotypes?
You can see the phenotype. A good way to remember is that a photograph is what you see. The genotype is the graphic representation of the trait.
What is the name of the chart that shows possible phenotypes and genotypes and genotypes?
punnet square
What might the phenotypes be of two organisms that were found to have different genotypes but the same phenotype?
Phenotypes refer to the visible traits (or characteristics). Genotypes are the underlying causes for those traits. There may be different genotypes that cause the same phenotype. If the observable traits from one individual are the same from another individual, one can say they have the same phenotypes.
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.
