A scientist carries out an experiment on a hamster. He exposes the hamster to x-rays at regular intervals. This results in a germ line mutation in the hamster. What is the possible outcome on the progeny of the hamster?

The defect is not carried forward to the progeny of the hamster.
The defect is carried forward to the progeny of the hamster.
The defect is lost in the progeny of the hamster.

I think the correct answer from the choices listed above is option B. The possible outcome on the progeny of the hamster would be that the defect is carried forward to the progeny of the hamster. Hope this answers the question. have a nice day

Answer:

The correct answer is that the defect is mediated forward towards the progeny of the hamster.

Explanation:

The germline mutations take place in the germ cells that afterward turns into sex cells and occurs as a modification in the germ cell's DNA. Unlike the somatic mutations, the germline mutations are hereditary in nature as they take place in the gametes that take part in the fertilization procedure.

Each gamete is accountable for half of the genetic substance to the zygote and influences only one of the two homologous chromosomes, that is, the one which is transmitted on from a modified parent germ cell. This develops a 50 percent chance that the mutated chromosome is transmitted to the progeny. The germline mutation is conducted by the whole organism, however, only half of the gametes possess the mutation. The germline mutation takes place at the time of meiosis, that is, at the stage of the embryo so it cannot be lost in the progeny.
