Unformatted text preview: iotic recombination Some of the gametes produce by the F1 have a different configuration of alleles as a result of crossing over between pr and vg+. This is relatively rare.

Rodriguez 2012 13 Crossing Over involves Chiasma Crossing over occurs at the "4 strand" stage of prophase I of meiosis and involves structures called "chiasma."

Rodriguez 2012 17 Linkage or eye color and wing shape alleles Previously, Mendel showed that a test cross for an F1 expressing 2 traits (dihybrid) produced a 1:1:1:1 ratio. However in the test cross below, Morgan found an exception t...
