A mаn hаs the twо hоmоlogous chromosomes shown in the box below. The blаck lines on each chromosome indicate the location of Gene A, Gene B, Gene C and D on each homolog. There are different alleles of these four genes. One chromosome has the A1, B1, C1 and D1 alleles, while the other chromosome has the A2, B2, C2 and D2 alleles. During meiosis, a crossover occurs between Gene A and Gene B, which is indicated by the red X. What will be the genotype of one of the recombinant chromosomes produced from this crossover?
