Answer:
The trait is Y-linked
Explanation:
The only plausible explanation behind the inheritance pattern shown by the porcupine trait is that it is <u>Y-linked</u>.
<em><u>Y-linked traits are limited to the Y chromosome only</u></em><em>, a sex chromosome that is peculiar to only the male gender. Chromosomally, females are XX while males are XY. Hence, only the male gender has the genetic capacity to inherit the porcupine trait. This is why only the sons of Edward Lambert, and never the daughters, exhibited the trait. </em>

It shows the three organisms to have evolved from a common ancestor.
Explanation:

The common ancestor might have evolved over time and in result, three different species were produced. It also shows that they are more closely related to one another than other organisms.
Other properties or traits that are common in these organisms are :
They all are mammals.
They are all livestock animals.
They all are multicellular organisms.
