Question
A cross between fruit files with genotypes Aa Bb × aa bb produces the following progeny:
10 Aa Bb 40 Aa bb 40 aa Bb 10 aa bb
Were the parental alleles in the coupling or repulsion configuration? Briefly explain
Expert Solution
Step 1
In a cross, the arrangement of linked alleles on the chromosomes is critical for determining the outcome. When two wild-type alleles are on one homologous chromosome and two mutant alleles are on the other, they are in the coupling configuration; when each chromosome contains one wild-type allele and one mutant allele, the alleles are in repulsion.
