What are Mendelian traits?
Traits that are controlled a multiple gene loci. Polygenic traits.
What are examples for the word allele?
The term allele is often used interchangeably with the word gene. Allele/gene is used for the variations seen at each gene locus for a trait on the homologous chromosome pair. For example: If there are three alleles for a trait only two of the alleles will be represented in the genotype of any one individual. The alleles for basic blood types A, B and O are examples. In general the term allele is not used interchangeably with gene in conjunction with the terms locus or loci..therefore Gene locus or gene loci but not allele locus or allele loci.
Can you get Lupus if you have the Lupus Gene?
There is no lupus gene. At this point, researchers have found 30 loci (locations) on the human genome that are implicated in the development of lupus.
What is it called when the phenotype is determined by more than two unlinked loci?
Polygenic inheritance.
If someone compares their number one chromosomes will they have very different gene loci?
I think so.
What are different forms of the same gene called and where is their precise location?
C) alleles, known as their loci
What is the definition of candidate gene testing?
A candidate gene is a probable cause for a disease. The gene can become a candidate based it's location is a chromosome region that is suspected of being the loci.
A characteristic of an organism that is determined by many genes?
The terms used to describe a number of genes on separate loci on the same chromosome (or another chromosome) which together determine a single phenotypic trait are polygene, multiple factor, multiple gene inheritance or quantitative gene.
What is linkage mapping?
Linkage map: A map of the genes on a chromosome based on linkage analysis. A linkage map does not show the physical distances between genes but rather their relative positions, as determined by how often two gene loci are inherited together.
An allele is either what two things?
Alleles are different forms of a gene found on chromosomes on sites called loci
What are non mendelian trait?
Traits that are controlled a multiple gene loci. Polygenic traits.
What is a DNA probe?
A Gene Probe is a term used to label several techniques used to identify a Gene Loci. a gene probe is often a piece of genetic material, that mirrors the target gene, and is also 'tagged' with dye so it can be identified.
