What are the two phenotypes?
For the pea plants, if the red allele is dominant and the white allele is recessive, only two phenotypes are possible. Both the plants with red-red and red-white genotypes will have the red phenotype, while the plants with the white-white genotype will have the white phenotype.
What are the 3 phenotypes?
If the only alleles for hair texture were straight and curly, there would be three phenotypes: straight, curly, and wavy. However, you asked for something a little different. You wanted three phenotypes that are all equally represented in the population.
How many types of phenotype are there?
With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
What is example of phenotype?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. … Examples of phenotypes include height, wing length, and hair color.
Which is a phenotype?
A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
How many genotypes do we have?
A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.
What is the phenotype of AA?
One allele is usually dominant. … The other allele is usually recessive which means it is only expressed if there are no alternate forms of the gene (other alleles) present. Therefore, both the genotypes AA and Aa produce a red feather phenotype.
What is a cell phenotype?
Cellular phenotype is the conglomerate of multiple cellular processes involving gene and protein expression that result in the elaboration of a cell’s particular morphology and function. … This single-cell study permits high resolution of molecular and functional components that underlie phenotype identity.
What is phenotypic expression?
Phenotypic expression is the result of a complex interplay between an organism’s genes and its environment. During growth and development, organisms undergo a programmed series of phenotypic changes. … The ability to vary phenotypic expression in response to environmental conditions is known as “phenotypic plasticity.”
What’s my phenotype and genotype?
An organism’s genotype is the set of genes that it carries. An organism’s phenotype is all of its observable characteristics — which are influenced both by its genotype and by the environment. A change in the environment also can affect the phenotype. …
What is heterozygous example?
If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair. The relationship between the two alleles affects which traits are expressed.
What are 3 examples of genotype?
Examples of Genotype:
- Height. For an individual’s gene makeup there is tall variety (T) and there is short variety (s). T and s are called the alleles. …
- Freckles or no freckles. Again the information that is passed from parent to child is carried in the cell of the genotype. …
- Lactose intolerance.
