What factors influence 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 can 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 are 3 factors that influence gene expression?

Various factors, including genetic makeup, exposure to harmful substances, other environmental influences, and age, can affect expressivity. Both penetrance and expressivity can vary: People with the gene may or may not have the trait and, in people with the trait, how the trait is expressed can vary.

How does genotype influence 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 determines or contributes to your phenotype quizlet?

your genotype is what makes your phenotype. your base sequence of a gene is what determines your allele- dominant or recessive, your two alleles determine ypur genotype, your genotype determines your phenotype. an organism’s genotype determines theor phenotype, because the genotype has the genes.

What factors increase gene expression?

In addition to drugs and chemicals, temperature and light are external environmental factors that may influence gene expression in certain organisms.

What are some factors that influence access and use of genetic information?

Other factors include the availability of quality genetic resources in the community, the appropriateness of genetic technologies offered to the community, the accessibility of clinical and genetic services, the costs and benefits of using genetic technology, and the community’s knowledge of the use of genetics to …

What are basal factors?

Basal, or general, transcription factors are necessary for RNA polymerase to function at a site of transcription in eukaryotes. They are considered the most basic set of proteins needed to activate gene transcription, and they include a number of proteins, such as TFIIA (transcription factor…

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 are three environmental factors that can influence plant phenotypes?

Environmental conditions, such as temperature and availability of nutrients can affect phenotypes.

What are the 3 types of genotypes?

There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.

What are 3 ways that the genotype determines 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.

Which traits are environmentally influenced?

Explanation: Environmental factors influence traits in plants and animals. These traits include things like weight, height, size, and color. If a child does not get proper nutrition, their height may be stunted as an adult.

What means 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.
