Question

a cat is ff and has short fur. short fur is the cat’s...
options: gene, phenotype, genotype, genetic disease, other:
a bird is aa and has long feathers. aa is the bird’s...
options: gene, phenotype, genotype, genetic disease

Explanation:

First Question (Cat with Ff and short fur):

• Gene: A gene is a segment of DNA, not a visible trait like short fur. Eliminate.
• Phenotype: Phenotype is the observable physical characteristic (like short fur) of an organism, determined by genotype and environment.
• Genotype: Genotype is the genetic makeup (e.g., Ff), not the visible trait. Eliminate.
• Genetic disease: Short fur is not a disease. Eliminate.

• Gene: A gene is a DNA segment, but "AA" is the combination of alleles (genetic makeup). Eliminate.
• Phenotype: Phenotype is the observable trait (long feathers), not the genetic code "AA". Eliminate.
• Genotype: Genotype is the genetic constitution of an organism (e.g., AA, representing the alleles for a trait).
• Genetic disease: "AA" is a genotype, not a disease. Eliminate.

Answer:

B. Phenotype

Second Question (Bird with AA and long feathers):
