Dominant genes will always be expressed however recessive genes would need to be inherited from both parents
Genes on the same chromosome are said to be linked
To see how close genes are on chromosomes. When crossing over occurs you can tell haw close genes are by the traits expressed independently. I f not expressed independently then these genes are probably linked by being close together on the chromosome and traveling as a pair during crossing over. A student of Thomas Hunt Morgan come up with the mathematical analysis of this phenomenom.
The term phenotype means what you see. Like black eyes or brown eyes or blue eyes. The same is for hair color. This is different from genotype which means what is in the genes or what genes are not expressed. A person with brown eyes can carry a gene for blue eyes. This is the genotype. Each person carries genes that are expressed or what are seen and also genes that are not expressed and are not seen.
They are operons. The genes contained in an operon are expressed together or not at all.
Dominant genes are genes that are expressed more readily than recessive genes, i.e. if you had a genotype that was AaBb, A being for brown hair, a for blonde hair, B for brown eyes, b for blue, you would have brown hair and brown eyes as the genes for those phenotypes are dominant. For recessive genes to be expressed in the phenotype the gamete needs to have recessive genes for both "slots", e.g. AA for blonde hair to be expressed or bb for blue eyes to be expressed. Edd
Chromosomes. Genes are currently being mapped for the correct "locus" or spot on the chromosome. Genes are traits that will be expressed based on dominance. Prime example, hair color.
RNA is the expressed form of a gene (which is DNA encoded). By isolating RNA, it is possible to determine which genes were being expressed and to what relative (or even absolute) level.
They are expressed.
Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.

Hox genes in mice and fruit flies are expressed similarly in that the genes themselves are similar enough to trade places and still function. The genes are expressed different because although you can switch the genes around, the outcome will result in the improper physical characteristic.

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.
No. Heterochromatic regions of DNA are not readily expressed as they are densely packaged. Some of these regions do not code for genes at all.
A dominant trait is expressed when two different genes for the same trait are present.
Dominant genes will always be expressed however recessive genes would need to be inherited from both parents
