Questions: The genes present on the chromosome are the and the actual bodily traits and characteristics that we see are the

The answer is the last one (or D): genotype; phenotype.

Explanation for each option:

1. Phenotype; genotype: This is incorrect because the phenotype refers to the actual bodily traits and characteristics that we see, while the genotype refers to the genes present on the chromosome.

2. Dominant traits; recessive traits: This is incorrect because dominant and recessive traits refer to the expression of certain genes, not the distinction between genes and physical traits.

3. Recessive traits; dominant traits: This is incorrect for the same reason as the previous option; it confuses the concept of gene expression with the distinction between genes and physical traits.

4. Genotype; phenotype: This is correct because the genotype refers to the genetic makeup of an organism (the genes present on the chromosome), and the phenotype refers to the observable physical traits and characteristics.

Summary: The genes present on the chromosome are the genotype, and the actual bodily traits and characteristics that we see are the phenotype.
