Explanation:
<u>Answer</u>: Option A Y-linked
<u>Explanation</u>:
- Y-linked traits are the ones which are due to the alleles present on the Y chromosome of an organism.
- Since, only the <em>male members</em> carry the Y chromosome, the traits linked to Y chromosome only pass down from the <em>father to the sons</em> and never to the daughters, such type of inheritance is known as Y linked inheritance.
- According to the question, the inheritance cannot be X linked because every daughter inherits one X chromosome from the father but the sons only inherit the Y chromosome. Thus, an<em> affected male cannot produce affected sons if the trait is X linked.</em>
- A <em>polygenic</em> trait is the one whose phenotype is determined by more than one genes, which again is not the case here.
- A <em>co-dominant</em> trait is the one which is determined by both the alleles i.e the phenotype is determined by both the alleles of a gene and none of the alleles is completely dominant over the other.
As can be seen from the question,<em> the affected father is producing an affected son and no affected daughter, thus this inheritance is Y linked.</em>
