Predict how the synaptic configurations of homologous pairs of chromosomes might appear when one member is normal and the other member has sustained a deletion or duplication.

a.
The deletion or duplication of any chromosome region will most likely be detrimental for its synapsis with a normal chromosome.

b.
There will be point-for-point pairing in all sections of the chromosome located between the centromere and the region of deletion or duplication. The rest of the chromosome will show no pairing.

c.
There will be point-for-point pairing in all sections of the chromosome located between the end of the chromosome and the region of deletion or duplication. The rest of the chromosome will show no pairing.

d.
There will be point-for-point pairing in all sections that are capable of pairing. The section that has no homolog will loop out to form a deletion or compensation loop.
