Practice question
Question
In a genetic map two genes A and B are 60 cM apart. If an individual heterozygous for the two genes (AaBb) is test-crossed, what percentage of the progeny will have the genotype aabb?
Explanation
In genetics and biotechnology, metabolic engineering and inheritance dictates that exogenous gene introduction and pathway extension enable trait improvement. Therefore 25 is correct as it demonstrates metabolic extension and combinatorial biosynthesis, supported by mechanistic studies and conserved across related systems.
