What factors influence phenotype?
Two factors that influence the phenotype are: (1) the specific genetic information of the individual (its genotype), and (2) environmental influences on the expression of the individual’s genetic potential.
What does the number of phenotypes depend on?
Having more than 1 or 2 alleles for a trait can greatly increase the number of phenotypes, depending on the trait’s specific pattern of inheritance. For example, human blood type is controlled by 3 alleles (just referring to the ABO blood groups here): A, B, and O.
How does the phenotype depend on its genes?
Genotype versus phenotype. 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. … For example, differences in the genotypes can produce different phenotypes.
Are phenotypes dependent on genotypes?
The sum of an organism’s observable characteristics is their phenotype. … Whilst a phenotype is influenced the genotype, genotype does not equal phenotype. The phenotype is influenced by the genotype and factors including: Epigenetic modifications.
What determines phenotype?
An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes. … Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What are 3 examples of phenotypes?
- Eye color.
- Hair color.
- 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.
What environmental factors affect phenotype?
Environment Can Impact Phenotype
Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all impact which of an animal’s genes are expressed, which ultimately affects the animal’s phenotype.
What is phenotypic evolution?
Phenotypic evolution occurs primarily by mutation of genes that interact with one another in the developmental process. … Novel mutations may be incorporated into the genome by natural selection (elimination of preexisting genotypes) or by random processes such as genetic and genomic drift.
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.”
How does genotype determine phenotype quizlet?
How does the genotype of an organism determine its phenotype? By specifying what kinds of RNA and which structural, enzymatic, and regulatory protein molecules are produced. -Polypeptides determine phenotype by acting as structural, enzymatic, and regulatory proteins.
