linkage group

الإنجليزية - الإنجليزية

تعريف linkage group في الإنجليزية الإنجليزية القاموس.: any pair of genes that tend to be transmitted together; "the genes of Drosophila fall into four linkage groups; A pair or set of genes on a chromosome that tend to be transmitted together. All the genes on a single chromosome. They are inherited as a group; during cell division they act and move as a unit rather than independently. Variations in linkage groups can occur if a chromosome breaks, and the sections join with the partner chromosome if it has broken in the same places. This exchange of genes between chromosomes, called crossing-over, usually occurs during meiosis. Sex linkage is the tendency of a characteristic to be linked to one sex; sex-linked traits in humans include red-green colour blindness and hemophilia
