According to Punnett Square, what can be concluded from Huntington's disease is that the disease is autosomal dominant.

Explanation:

Huntington's disease is characterized as a neurodegenerative condition, which affects body movements and progressively decreases some higher brain functions.

Inheritance plays a determining role in Huntinton's disease, being a disease transmitted from parents to children with an autosomal dominant pattern, that is, all individuals with the defective gene (H) will have the disease, while the absence of the gene (rr) also guarantees the absence of this condition.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
