When cross-1 is done between white mutant A and white mutant B, the resulting F1 progeny is wild type (Purple). Analyze the results obtained from self-fertilization between F1 progeny and determine phenotypic ratio and phenotypic distribution among F2 progeny. Introduction: The condition mentioned above can be answered with the help of complementation test. Complementation test is performed in such a situation as it helps us understand whether the mutation that has occurred is cis mutation (mutation in same gene) or trans mutation (mutation in different set of gene). Complementation occurs when the progeny with normal (wild type) phenotype is observed from crossing between two organisms with different homozygous recessive mutation. On the other hand, complementation is not observed when mutation is in the same gene. Mendel's second law is the law of independent assortment. According to this law, when cross is done for more than one trait (two or more), the traits organize independently (selection of one trait is not dependent on another), so different phenotypes may occur with equal probability.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
