Company Profile:
The presence of different alleles at one or more loci on homologous chromosomes..
Industry:Biology
See: heterozygosity.
Industry:Biology
DNA sequence that is very similar across several different types of organisms. See also: gene, mutation.
Industry:Biology
A fast method of determining the order of bases in DNA. See also: sequencing.
Industry:Biology
A short stretch of nucleotides whose base sequence is virtually identical in all the genes that contain it. Homeoboxes have been found in many organisms from fruit flies to human beings. In the fruit fly, a homeobox appears to determine when particular groups of genes are expressed during development..
Industry:Biology
A member of a chromosome pair in diploid organisms or a gene that has the same origin and functions in two or more species..
Industry:Biology
Chromosome containing the same linear gene sequences as another, each derived from one parent..
Industry:Biology
Swapping of DNA fragments between paired chromosomes..
Industry:Biology
Similarity in DNA or protein sequences between individuals of the same species or among different species..
Industry:Biology
An organism that has two identical alleles of a gene. See also: heterozygote.
