For example, can the alleles for the body color gene (brown and black) be mixed and matched in different combinations with the alleles for the eye color gene (red and brown)? The simple answer to ...

New research from The Jackson Laboratory (JAX) shows that genetics significantly impact eye aging, with different genes affecting retinal aging in unique ways. Traditionally, studies of retinal ...

Sturtevant examined recombination events between B (body color), CO (two eye color genes that were closely linked), and R (rudimentary wings), and compared the frequencies of crossover events.
