Organisms of the same species with different genotypes can show differing norms of reaction when different phenotypes are measured or when environmental variables are altered. Therefore, a different norm of reaction exists for every combination of genotype, phenotypic trait, and environmental variable studied.

Moreover, Can organisms with the same genotype have different phenotypes?

Can organisms with different genotypes have the same phenotypes? ... The answer is yes, two different genotypes can result in the same phenotype. Remember, the recessive phenotype will be expressed only when the dominant allele is absent, or when an individual is homozygous recessive (tt) (Figure below).

Likewise, How many different phenotypes are possible?. Even though only four different phenotypes are possible from this cross, nine different genotypes are possible, as shown in Figure 13.

Hereof, Can phenotype be changed?

The phenotype may change constantly throughout the life of an individual because of environmental changes and the physiological and morphological changes associated with aging. ... Three types of natural selection, showing the effects of each on the distribution of phenotypes within a population.

What allows your cells to have different phenotypes?

Gene regulation makes cells different

These different patterns of gene expression cause your various cell types to have different sets of proteins, making each cell type uniquely specialized to do its job.

What is phenotype example?

Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.

What is a genotype vs phenotype?

A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics.

What are 3 examples of phenotypes?

Phenotype Examples
  • Eye color.
  • Hair color.
  • Height.
  • Sound of your voice.
  • Certain types of disease.
  • Size of a bird's beak.
  • Length of a fox's tail.
  • Color of the stripes on a cat.

Is phenotype inherited?

The sum of an organism's observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism's parents, the phenotype is not.

Which is the best description of 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.

Is red hair a phenotype?

Red hair is a recessive trait meaning you need two broken MC1R copies to end up with it. ... Genotype is the genes that we have and phenotype is the trait those genes give us.

Is BB a genotype or phenotype?

Phenotype. The physical appearance of the genotype is called the phenotype. For example, children with the genotypes 'BB' and 'Bb' have brown-eye phenotypes, whereas a child with two blue-eye alleles and the genotype 'bb' has blue eyes and a blue-eye phenotype.

How many genes for each trait does a child inherit?

Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color.

Is AA heterozygous or homozygous?

Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.

Is personality a phenotype?

Personality phenotypes are extremely variable. Minor variations in measures and samples influence the number and contents of factors identified. Confidence in any structure would, therefore, be increased with evidence that the phenotypic structure reflects an underlying genetic architecture.

Is Behaviour a phenotype?

A behavioural phenotype refers to observable characteristics that occur more often in individuals with a specific genetic syndrome than individuals without that syndrome. Whilst a behavioural phenotype describes observable behaviour, the term 'endophenotype' describes characteristics that are not directly observable.
