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 and it includes the genes (sequence of nucleotides). The example of genotypes includes genes for eye, hair, and nose development. The phenotype is the external expression of the physical traits of the organism. 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 genes of the organism. The phenotype consists of the external visible characteristics of the person.

You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different.
