Concept explainers
The genetic makeup of an organism is called its ______, and the physical traits of an organism are called its _____.
To analyze: The genetic makeup of an organism and the physical traits of an organism.
Introduction:
The genotype consists of the genes that define the genetic composition of an organism. The phenotype consists of the external visible characteristics of the organism.
Answer to Problem 1SQ
Correct Answer: The genetic makeup of an organism is called its genotype, and the physical traits of an organism are called its phenotype.
Explanation of Solution
The genotype consists of the entire genetic composition of the organism. It includes the genes and their sequences. The phenotype is the external expression of the physical traits of the organism. The examples of genotypes include genes for eye, hair, and nose development. They are the external visible features of the organism. The examples of phenotype include eye color, hair color, and skin color.
The genotype consists of the genetic composition and the genes of the organism. The phenotype consists of the external visible characteristics of the person.
