Environment and phenotype
Phenotype: phenotype, all the observable characteristics of an organism that result from the interaction of its genotype (total genetic inheritance) with the environment. A phenotype is a trait we can observe genes carry instructions, and the result of our body following those instructions (for example, making a pigment in our eyes), is a phenotypic trait, like . Best answer: one example i can think of is height your genetics determine how tall you might be able to grow up to, but environmental factors (eating habits .
In other words, the phenotype depends not only on the genotype and environment, but it depends specifically upon which genotype and environment are under consideration although the above example used fish, the example actually reflects the work of falconer (1960) who demonstrated the importance of genotype by environment interactions when . Effects of the interaction between genotype and environment research into the genetic epidemiology of alcohol dependence andrew c heath, dphil, and elliot c nelson, md. The epigenome is the primary location of gene-environment interactions and can be altered by the environment both directly and indirectly it literally means “on top of or in addition to genetics ,” or basically factors outside of the genetic sequence.
Genotype, environment, phenotype every living organism is the result of evolution that works by the same basic principle the genotype or genetic code carries all the genetic information regarding growth, appearance, and all the characteristics we can later observe. Gene-environment interactions can modulate the adverse effects of an allele that confers increased risk of disease, or can exacerbate the genotype-phenotype relationship and increase risk, in a manner often referred to as nutrigenetics. Environmental impact on height in humans an organism’s final appearance (phenotype) is a result of the interaction between the information held in its genotype and the effect of the environment . If genotype can be used to reliably predict phenotype, the phenotypic plasticity is low overall, the amount of influence that environmental factors have on your ultimate phenotype is a hotly debated scientific issue.
How genotype affects phenotype thus genes, proteins, other chemicals inside the cell, intercellular interactions and the external environment all affect the trait. Best answer: the genotype affects the phenotype, and the phenotype may show up by itself due to the genotype or due to environmental conditions for example, you . Transcript of the effect of the environment on the phenotype of the hydran if all hydrangea flowers contain anthocyanin delphinidin 3- glucoside what causes color variation this research suggest that the enzyme causes ph shift, which causes the shape of the petal to change.
The physical expression of a genotype is referred to as a phenotype, which is simply defined as the traits that the environment pulls out from the plant’s genetic code. To investigate the effect of one environmental factor on the phenotype of pea plants background information: pea seeds are available with identical genetic information for height – tall or dwarf peas. An individual’s phenotype is controlled in large part by the genotype, but the environment plays a role as well a wolf may have a genotype that calls for a long coat of fur, but if she gets infested with ticks and rubs her fur off, the phenotype will be an individual with bare spots. A phenotype results from the expression of an organism's genetic code, its genotype, as well as the influence of environmental factors and the interactions between the two when two or more clearly different phenotypes exist in the same population of a species, the species is called polymorphic .
Environment and phenotype
The genotype of an organism is the genetic code in its cells this genetic constitution of an individual influences – but is not solely responsible for – many of its traits the phenotype is the visible or expressed trait, such as hair color the phenotype depends upon the genotype but can also . Epigenetics is the study of heritable changes in gene expression (active versus inactive genes) that do not involve changes to the underlying dna sequence — a change in phenotype without a change in genotype — which in turn affects how cells read the genes epigenetic change is a regular and natural occurrence but can also be influenced by . Phenotype, genotype and environment definitions phenotype the physical characteristics of an organism - determined by genotype and environment for example weight - people have natural body types such (endomorph, ectomorph etc) but the environment (how much fat they eat) can also affect this. Aim: to investigate the effect of one environmental factor on the phenotype of pea plantsbackground information: pea seeds are available with identical genetic information for height - tall or dwarf peas.
Now the terms phenotype, genotype and environmental influence will be considered generally it is a fact that the phenotype of an animal is determined by its genotype and its environment often it is assumed that the phenotype is the sum of the genotype and the environment the phenotype can also be seen as the interaction between genetics and environmental factors, some genotypes are better . Phenotype is what you see - the visible or observable expression of the results of genes, combined with the environmental influence on an organism’s appearance or behavior for example: it is the expression of gene information which is observable with the senses (like the sound of a bird’s chirping or the color of a cat’s hair).
Aim: to investigate the effect of one environmental factor on the phenotype of pea plants background information: pea seeds are available with identical genetic information for height - tall or dwarf peas. Phenotype is determined by environmental factors from the moment of conception till the day we die by many affects and reasons: nutrition, temperature, humidity, pollution, drugs (drug abuse), radiation, ultraviolet ray penetration, aging, and the list goes on and on. Phenotypic discordance between monozygotic twins, such as a difference in disease susceptibility, implicates the role of the environment in determining phenotype to assess genomewide environmental effects on “gene expression phenotype,” we employed a published microarray data set for twins we .
