Graphic representation of 2:2 segregation types during meiosis in a rcp(3;6) individual. a Material exchange in a reciprocal translocation resulting in an expected quadrivalent pairing. Alternate segregation (the usual type of 2:2 segregation) results in balanced gametes with normal chromosomes (b) or derivative chromosomes (c); and adjacent-I segregation leads to unbalanced gametes with one derivative chromosome and the normal chromosome of the other pair (d and e). Adjacent-II segregation leads to unbalanced gametes with two copies of the same chromosome (one normal and one derivative) and no copy of the other chromosome (f and g)
