There are several ways of finding genes, including:
- labeling and detecting DNA binding proteins that you think may bind to your gene of interest (DNA combing)
- taking the cDNA of a protein coding gene and tracing it back into the genome
- making a labeled complimentary probe of the gene, denaturing the genome, and hoping that your probe finds its complimentary match
- sequencing and trying to locate regions that look like a predicted sequence
- transforming a population of cells with a vector (that contains a selectable marker) of the organism of interest's genome, and selecting for that gene using that marker or different properties of the gene (especially if the species of cells you've chosen can transcribe/translate inserted genes)
There are probably numerous more general methods, but that's just a few :)

The chromosome
By exploring in biological databases such as NCBI you can find the specific genes of any organism. By aligning the genes of Candida with related species of bacteria or fungus one can fish out the unique genes of Candida that are not common in other organism. There are tools for these sequence alignments (eg:BLAST, FASTA)

After performing his experiments on hybridization in garden pea Mendel concluded that (1) genes segregate in the next generation from parents to the offsprings and (2) the assortmant of genes is independent during gamete formation.
the genus of a mongoose is 'Herpestes' soz i couldn't find the species
he unraveled the chromosomes_______________________________________________________________________ cbuck
one of the laws that can help you find a law that can tell you about nature is the laws of heredity. These laws explain how genes are inherited, but do not explain how genes work.
dont trip gene mapping is a procedure by which you find out what type of genes are present in the chromosomes of a living organism. you identify the location of genes also. for example the gene mapping of human was completed in 2001-2003 because humans have 45 chromosomes and approximately 35000 genes. so to identify such a large amount of genes and to find out their location, the scientists of the world distributed the task among themselves but still it took several years!!
Red (AKA chestnut) and Black. In the related links you will find a page that can tell you a ton about the red and black genes, as well as how they work with other genes. *Note: it says Morgan horses, but it goes for all breeds*
Polygenic genes are usually dominant genes.
