How to perform a testcross

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. WebMar 31, 2024 · The F1 males carried the three recessive mutations on their single X chromosome. Thus, this intercross was equivalent to a testcross with all three genes in the F1 females present in the homozygous form. The F2 progeny flies from the intercross comprised eight phenotypically distinct classes, two of them are parental and six …
