A child with the genes for PKU (a recessive disorder that leads to brain damage because proteins aren't digested properly) is raised to adulthood under a strict low-protein diet that prevents the gene from being activated. He lives a normal life and eventually becomes a father. As a genetic counselor, explain whether the fact that his gene is inactive affects the probability his future children might inherit the PKU allele. Be complete. Explain the reasoning you used to reach your conclusion.

Answer:

Even if the gene is inactive, you can inherit the gene from your children.

Explanation:

Genetic inheritance is determined by the patterns that are dominant or recessive, not with the activation or not of the gene that you already possess, so depending on whether your partner is a carrier of the gene, there will be a greater probability of inheriting it from your children, even if your partner is a non-carrier of the gene none of the descendants inherits the condition, but they are all carriers, if their partner is a carrier but does not affect it, there is a 50% probability that one descendant is affected, and the rest are carriers but not inherited the condition, if their partner is a carrier, there is a 25% probability that a descendant is affected, a 50% probability that they are carriers but without manifesting the condition, and a 25% probability of not having any recessive allele.

In this case, the inactive gene of man affects the probability his future children might inherit the PKU allele - remain same or 1.

PKU is a latent ailment recessive disorder that leads to brain damage because proteins aren't digested properly, and the man in this issue is two alleles of the recessive allele.

he carries on with a typical life by staying away from protein-rich sustenance

he conveys those passive alleles in his genome when he creates gametes with passive alleles.

on the off chance that P is overwhelming ordinary allele and p is latent allele.

man is pp and gametes he creates are p so the majority of his descendants will have this allele p

so the likelihood that he will acquire this allele p to his youngsters is 1 since the majority of his gametes contains p allele.

The probability of inheritance of that gene remains the same

Thus, In this case, inactive gene of man affects the probability his future children might inherit the PKU allele - remain same or 1.
