a gene(s) are special cells that you get from youre parents genes determine what you look like as you were born and as you turn into an adult these cells determine what kind of characteristics you get meaning if you look like your dad or mom
A piece of DNA which controls a trait is a gene variations of a gene are called alleles. If you mean "controls how much a particular trait is expressed" then you would be dealiung with the promoter region of a gene which is near the start and controls how strongly a gene is expressed.
The non-coding sections of a gene are known as introns. The coding sections of a gene are known as exons.
I assume you mean the lac operon. The repressor binds upstream of the gene(s) in the regulatory gene region.
Additive gene action is estimate of the quantitative change in a trait. Additive effect= mean of superior parent - mean of inferior parent Dominace effect = Mean of F1 hybrid - mean of both parent Epistatic = additive x additive = additive x dominace = dominace x dominace
If you carry the sickle cell gene, it doesn't really mean much as far as your own personal health goes. Except that you are less likely to get malaria. However, if you decide to have kids, and whoever you mate with also carries the sickle cell gene (not the full blown disease/gene) , your child has a chance of having sickle cell disease (full blown).
How is a gene not expressed
Gene Okerlund goes by Mean Gene.
The cast of Mean Gene - 2017 includes: Gar Rogala as Gene Russet
Gene Snisky goes by Mean Gene, Gene Sinisky, Gene Snitsky, and The Foot Freak.
Mean Gene Kelton was born on April 10, 1953, in Mississippi, USA.
Do you mean allele? An allele is a different molecular form of the same gene.
Mean Gene Kelton died on December 28, 2010, in Houston, Texas, USA of road accident.

When we say that a gene is expressed, it means that the information encoded in the gene is used by the cell to make a specific protein or functional RNA molecule. This process is known as gene expression.
A single abnormal gene produces HD. In 1993, scientists finally isolated the HD (Huntington's Chorea) gene on chromosome 4.
gene is a specific region of chromosome
its means race/kind
