Can you give an example of genotypes and phenotypes that can be influenced by the genotype and the environment?
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 single base pair mutation that lead to sickle cell anemia is a classic example.
What is an example of a trait that is influence by both genetic and environmental variation?
Weight and height are common examples of characteristics that are influenced by both genetic and environmental factors.
What are some examples of traits influenced by genes?
Genes play a greater role in forming character traits — such as self-control, decision making or sociability — than was previously thought, new research suggests. A study of more than 800 sets of twins found that genetics were more influential in shaping key traits than a person’s home environment and surroundings.
What is an example of a genotype and phenotype?
An organism’s genotype is its specific combination of alleles for a given gene. So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism’s allellic combination (genotype).
Is phenotype influenced by environment?
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 two things influence an individual’s 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 are traits influenced by the environment?
Explanation: Environmental factors influence traits in plants and animals. These traits include things like weight, height, size, and color. If a dog does not get proper nutrition and exercise, their weight will be negatively impacted.
What are 2 examples of the influence of environment on personality?
One environmental influence on personality is culture. For instance, some cultures dictate that children should be reserved and speak only when spoken to. Another environmental influence is school. Since children spend the majority of their time in school, this can have a huge influence on their personality.
Which is an example of environmental influence on gene expression?
Drugs and Chemicals The presence of drugs or chemicals in an organism’s environment can also influence gene expression in the organism. Cyclops fish are a dramatic example of the way in which an environmental chemical can affect development.
How could two individuals with the same genotype have a different phenotype?
Mandira P. Same phenotype but different genotype is possible due to presence of dominant allele. A person can have a dominant allele on both the homologous chromosomes (i.e. in double dose) while another person may have single dominant allele and a corresponding recessive allele.
What is an example of a genotype?
The subsequent combination of alleles that an individual possesses for a specific gene is their genotype . Let’s look at a classic example – eye color. A gene encodes eye color. In this example, the allele is either brown, or blue, with one inherited from the mother, and the other inherited from the father.
What are the factors that influence the phenotype of an organism?
The phenotype is influenced by the genotype and factors including: Epigenetic modifications Environmental and lifestyle factors Figure 2: Flamingos are naturally white in color, it is only the pigments in the organisms that they eat that cause them to turn vibrantly pink. Phenotype examples
Which traits are environmental traits?
These traits are environmental traits because they are traits that you choose or learn, or that are influenced by the place you live. Things that can affect the characteristics of an organism include temperature, nutrition, exposure to the Sun, disease, injuries, and living conditions.
How does natural selection affect genetic variation?
In natural selection, organisms with environmentally selected traits are better able to adapt to the environment and pass on their genes. Major causes of variation include mutations, gene flow, and sexual reproduction. DNA mutation causes genetic variation by altering the genes of individuals in a population.
