Chapter 18: Q. 6 (page 464)

Which description is an example of a phenotype?

a. A certain duck has a blue beak.

b. A mutation occurred to a flower.

c. Most cheetahs live solitary lives.

d. both a and c

Short Answer

Expert verified

Option a is correct.

Step by step solution

01

Introduction

Two primary processes鈥攎utation and sexual reproduction鈥攁re responsible for the genetic variety in a population. The primary source of new alleles, or new genetic variation in any population, is a mutation, a change in the DNA. Three possible phenotypic consequences can result from the genetic changes a mutation brings about.

02

Explanation for correct option

The correct option is A.

The term "phenotype" describes a person's distinguishable characteristics, such as height, eye color, and blood type. Both a person's genomic makeup (genotype) and environmental circumstances affect their phenotype. The phrase "blue beak" describes a phenotypic trait of a particular individual duck.

03

Explanation for incorrect option

b. Describes a change in the genotype of the organism

c. Describes a quality of "most" cheetahs and is not specific to an organism
