Given that the mother cell is heterozygous for both genes A and B (genotype= A/a;B/b) and two of the chromosomes are drawn correctly below, choose the possible copies of chromosomes and place a single chromosome at each of the two positions P1 and P2 respectively. When you drop the correct chromosome onto an allowed position, you will see the box underneath the chromosome turn green as well as receive a congratulatory popup-box message. If you try dropping an incorrect copy of a chromosome onto one of the positions, the box will stay yellow and you will be given another chance to place the chromosome.
Please try to explain why only some arrangements of chromosomes are possible due to the processes of crossing over and independent assortment that happen during meiosis.
