If the genes are loosely linked, these tetrad genotypes can also arise as a consequence of a three-strand double cross-over between X and Y (or Y and Z ) and a third cross-over between Y and Z (or X and Y ), but the strand-relationships with the third cross-over are two- or ...

Genes which are 'linked' and are situated on same chromosome, cannot 'separate' during gametes formation and hence cannot assort independently.

Sex chromosomes are the chromosomes which determine the sex of an organism. Learn more about the exceptions to independent assortments, sex- linked and sex-limited traits as well as carriers of disadvantageous genes. Taking the Hamster by the Horns So as Adrian has been performing his flying ...
We obtained several clones containing partial or complete repeats of both multigene families in which both types of genes displayed the same orientation. We provide a comprehensive collection of razor shell 5S rDNA clones, both with linked and nonlinked organisation, and the first bivalve U1 snDNA...
