What can influence genes besides traits?
The environment.
What is a description for phenotype and example?
The phenotype is a physical characteristic that is expressed by the genes. ----- An example of a phenotype is human blood group.
The set of characteristics that an individual develops due to the combined influence of genes and environment is called a?
Phenotype.
Can a individual carry a gene that is not expressed?
not usually, most books fit into the normal genres: mystery, fiction, nonfiction, adventure etc. I believe this person is referring to "genes," not "genres." To answer the question, then: yes, you can have genes that are not expressed. Recessive genes, for example, will not be expressed in heterozygous individuals; they will only be expressed in homozygous recessive individuals. For example; if you have the genotype Aa, the recessive gene - "a" - will not be expressed because the genotype contains a dominant allele, and the dominant allele will always be the one expressed. The only way that the "a" allele will be expressed is, again, if you are homozygous for that recessive gene (your genotype would be aa).
What is the relationship between genes and the environment?
Genes are regulated through a number of ways. Some can be regulated by the environment you're in. For example, if you're in the sun a lot, genes will get turned on or up to increase the production of skin pigmentation so you get tanned. When you stay out of the sun, the genes turn off and your skin gets lighter.
What can influence genes besides traits?
The environment.
Some aspects of a person may be predetermined at birth by his or her genes. However, a person's environment can change how the genes are expressed and can change who the person becomes This is an example of the _____ debate?
Nature versus Nurture >:(
Genetic traits are formed by what?
Genetic traits are formed by both genes and the environment. For example, genes and environmental factors such as exposure to cigarette smoke can both influence aging.
Some mammals have genes for fur color that produce pigment only when the outside temperature is above a certain level This pigment production is an example of how the environment of an organism can?
influence the expression of certain genes
What does epigenetics reveal about the nature versus nurture debate?
Epigenetics states that the environment can influence the way certain genes are expressed. What this reveals about the nature vs. nurture debate is that it may not be a battle between the two. These two influencing components may work hand in hand all through out our lives, making it more like nature via nurture. We may inherit certain genes, but the environment may be the deciding factor when it comes to which genes will be expressed and how strongly.

What can affect an organism trait?
genes and the environment
What besides genes influence traits?
The environment.
An expressed gene is one that?
is transcribed into RNA. Promoters (I think that's what you meant, right?) don't function as genes; they stand as a signal for RNA polymerase to begin transcription of the actual gene, which begins about 25 base pairs downstream of the promoter region in eukaryotic DNA. Expressed genes DO code for proteins, but not all protein-coding genes are expressed. For example, the cells in your heart contain genes that code for proteins needed only in your liver. While those genes definitely code for proteins, they're not expressed. Expressed genes (and non-expressed genes, Ke$ha Looks like a man, for that matter) are made of DNA, not mRNA.

What can sometimes influence expression of genes?
Several factors determine the final outcome of gene expression. They include the cell's environment, the presence of other cells, and the timing of gene expression. hope this helped! -Steph
