The genotypes in which one or more alleles is dominant.
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.)
For a single gene trait with two alleles, one dominant and one recessive, there are three possible genotypes: homozygous dominant (AA), heterozygous (Aa), and homozygous recessive (aa). In terms of phenotypes, there are typically two: the dominant phenotype (AA and Aa) and the recessive phenotype (aa). Thus, there are three genotypes and two phenotypes for this trait in the population.
By observing the phenotypes of individuals in a pedigree (such as their physical characteristics or traits), one can infer the genotypes that may be responsible for those traits. By looking at patterns of inheritance within the pedigree, such as autosomal dominant, autosomal recessive, or X-linked inheritance, one can make educated guesses about the genotypes of individuals based on their observed phenotypes. However, the presence of genetic variability, incomplete penetrance, or phenocopies can complicate the prediction of genotypes solely based on phenotypic information.
No.
Phenotypes are the entirety of the observable traits. Genotypes are the instructions in the genetic code. Dominant alleles override the recessive alleles, making only the dominant alleles expressed.
To accurately determine the possible phenotypes of the offspring from the parental plants in problem no. 1, the specific traits and genotypes of the parent plants need to be provided. Typically, the phenotypes will depend on whether the traits are dominant or recessive and the alleles involved in the cross. If you provide the parental genotypes or the traits being studied, I can give a more precise answer regarding the potential phenotypes of the offspring.
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.
Indirectly, yes it does. But it can only act on genotypes through their phenotypes.
A Punnet square is used to find the probablitiy of certain genetic traits in the offspring of an organism (example: the traits in the children) by taking the trait of each possible parent gamete (sex cell) and combining the combinations within the squares.Example:A aA AA Aaa Aa aaSo the offspring here have a 25% chance of being homozygous (both dominant) dominant for the trait, 50% heterozygous (one dominant and one recessive) dominant for the trait, and 25% (homozygous (both recessive)) recessive for the trait.
The tall pea plants have the phenotype of tall height. Their genotypes can vary depending on whether they are homozygous dominant (TT) or heterozygous (Tt) for the tall trait.
The diagram can be used to predict the genotypes and phenotypes of offspring by following the inheritance patterns of the parents' traits. By analyzing the alleles passed down from each parent, one can determine the possible combinations of genotypes and corresponding phenotypes that the offspring may inherit.
Many possible genotypes, producing ,any possible phenotypes.
