What factors affect the phenotype of an animal?
Feb 14, 2020 · 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. How does genotype influence phenotype? Genotype versus phenotype. An organism's genotype is the set of genes that it carries.
What factors affect phenotypic expression?
But, there are also environmental factors that can shape our phenotype. Let's take a look at two examples. Mutations Although the sun can feel great on …
How does genotype affect our 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 best describes a phenotype? A phenotype is an individual’s observable traits, such as height, eye color, and blood type.
What is the phenotype of an organism?

What are the factors that affect 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 best describes 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.
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.
How do genes affect phenotypic expression?
The genome in which a genotype is found can affect the expression of that genotype, and the environment can affect the phenotype. Genes can also be pleitropic when they affect more than one trait. The more loci affecting the trait, the greater number of phenotypic classes.
What is the mechanism of gene regulation?
Mechanisms of gene regulation include: Regulating the rate of transcription. This is the most economical method of regulation. Regulating the processing of RNA molecules, including alternative splicing to produce more than one protein product from a single gene.
What is positive gene regulation?
Regulatory Proteins. Positive Regulation. The binding of specific protein (activator) is required for transcription to begin. DNA bound activators can regulate transcription by helping with ignition. To do this they sometimes tether RNA polymerase to the promoter.
Which of the following is an example of positive gene regulation?
So, the correct option is ‘The tryptophan gene, in which the presence of tryptophan functions as a corepressor to prevent its own transcription.
What factors affect phenotype?
An organism’s phenotype results from two basic factors: the expression of an organism’s genetic code, or its genotype, and the influence of environmental factors. Both factors may interact, further affecting phenotype.
How does the genotype affect the phenotype?
Genotype & Phenotype. Definitions: phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). … In a narrow “genetic” sense, the genotype defines the phenotype.
What is the alternative form of a gene?
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. … Each pair of alleles represents the genotype of a specific gene.
Do alleles have phenotypes?
Alleles produce phenotypes (or physical versions of a trait) that are either dominant or recessive. The dominance or recessivity associated with a particular allele is the result of masking, by which a dominant phenotype hides a recessive phenotype.
What environmental factors affect 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.
How does genotype and environment affect 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.
What is the process called when one genotype gives rise to a different phenotype under different environmental conditions?
Phenotypic plasticity can be defined as ‘the ability of individual genotypes to produce different phenotypes when exposed to different environmental conditions’ (Pigliucci et al. 2006).
How both environment and genetics contribute to phenotype?
Environmental conditions, such as temperature and availability of nutrients can affect phenotypes. For example, temperature affects coat color in Siamese cats. ... Height in humans is a complex phenotype influenced by many genes, but it is also influenced by nutrition.
How does 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 the two main factors responsible for phenotypic variation?
Two types of factors are recognized as contributing to the phenotypic variation in a population, genetic and environmental.
What is influenced by both genetic and environmental factors?
Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors. Intelligence is challenging to study, in part because it can be defined and measured in different ways.
What are the contributing factors of one's character?
Such examples include cultural factors, family, religion, school, jobs, etc. The field of psychology recognizes what are referred to as the "Big Five" personality factors, also sometimes called the Five Factor Model. These five traits are believed by some to be a key aspect to human personality.
What are the top 3 factors influencing personality development?
The factors are: 1. Biological Factors 2. Cultural Determinants of Personality 3. Family Influences on Personality Development.
Which factor is important for development of one's personality examples?
To shape a one's personality, the environment plays an important role. Apart from that, genetics, and life experiences also play an important role say for instance parents, teachers, and friends influence the development of a person right from tender age.
