Question

1. which of the following best describes the relationship between genes and traits in cheetahs?

genes direct the production of proteins, which influence traits like spot shape and distribution.
proteins are made randomly and have no impact on a cheetahs appearance.
traits like spot patterns are random and unrelated to genetics.
genes control the environment, which creates traits like spots.

<reasoning>

Analyze the central dogma of molecular biology

Genes contain the instructions for building proteins. These proteins then perform essential cellular functions that directly determine physical traits.

Evaluate the first option

Genes direct protein synthesis. These proteins shape physical characteristics, such as cheetah spot patterns. This aligns with biological principles.

Evaluate the second option

Protein synthesis is highly regulated, not random. Proteins directly determine cellular structure and organism appearance. This option is incorrect.

Evaluate the third option

Physical traits like spot patterns are inherited. They are determined by genetics, not random environmental noise. This option is incorrect.

Evaluate the fourth option

Genes code for internal biological molecules. They do not control the external environment. This option is incorrect.
