For example, we carry out the test cross and obtain 400 progeny. These progeny are sorted into phenotypes and we discover that we have 200 flies with gray body and red eyes, and 200 progeny with gray bodies and pink eyes.

A Simplified Comparison of Reciprocal Cross Vs. Test …

WebThe testcross is powerful because it allows you to follow the meiotic events in one parent because all of the gametes from the test cross parent are homozygous recessive. For this example, the testcross genotype is pr vg. Therefore the testcross progeny will represent the distribution of the gametes in the F 1. WebA test cross between two genes is called a two-point test cross. Let us explore a worked example which will demonstrate how we are able to gene map using recombination frequencies. First, we will look at two-point test crosses, then we will investigate three-point test crosses, which are generally more accurate.
