It has been suggested that any maledetermining genes contain

It has been suggested that any male-determining genes contained on the Y chromosome in humans cannot be located in the limited region that synapses with the X chromosome (the PARs) during meiosis.

What might be the outcome if such genes were located in this region, i.e. located in the PAR region?        

Sex-determining loci on the Y chromosome would be inhibited and no offspring would be produced.

Sex-determining loci on the Y chromosome would be mutated which causes diseases in the offspring.

Sex-determining loci on the Y chromosome would be transferred through crossing over to the X
chromosome

Sex-determining loci on the Y chromosome would be affected and hermaphrodite feature would develop.

Solution

Option d. Sex-determining loci on the Y chromosome would be affected and hermaphrodite feature would develop.

Structural and/or genetic dissimilarity between the pseudoautosomal regions of the X and Y chromosomes can disrupt pairing and recombination, and consequently cause male infertility.
