Why do you have more genotypes than phenotypes?
Because those alleles segregate, or seperate, and combine again to make different alleles, thus making different phenotypes.
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.
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.
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.
How can you have the same phenotype but different genotype?
Different genotypes don't always change your phenotypes because of mutations
Which genotypes have dominant phenotypes?
The genotypes in which one or more alleles is dominant.
Can phenotypes OB produce genotypes As?
No.

What is the Punnett square used to determine?
A punit square is essentially a method to work out the possible offsprings of a cross. The information is presented in a tabular for better understanding. The square is used as a tool in genetics to calculate the genootypic and phenopypic rations of certain crosses. The alleles of the parents are places on the two sides of the square and by filling in the grid, we find out the possible outcomes of the cross and determine the genotypic and phenoypic ratios
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.
