Two puppies are born in the same litter. One has blue eyes and the other has brown eyes. Develop a hypothesis as to why the puppies have different eye color. Justify your hypothesis in two or more complete sentences in the essay box below.

Hypothesis: Eye color in puppies is determined by genetic inheritance from their parents. The blue-eyed puppy likely inherited a recessive gene for blue eyes from both parents, while the brown-eyed puppy received a dominant gene for brown eyes from at least one parent.

Hypothesis: The difference in eye color between the two puppies in the same litter can potentially be attributed to variations in their genetic makeup.

Justification: Eye color is primarily determined by the presence of specific genes that code for pigment production in the iris. It is possible that the puppy with blue eyes inherited a set of genes that limits or prevents the production of pigments, while the puppy with brown eyes inherited a set of genes that promote pigment production. This genetic variation within the same litter could explain the difference in eye color observed in the puppies.
