Chapter 13, Problem 8STP

Summary Introduction

Introduction :

The eukaryotes such as plants, animals and fungi carry in their cells either one chromosome set (haploid) or two sets (diploid). In these species, the haploid and diploid is the normal status of chromosomes. Organisms with multiples of the basic chromosome set are called euploid.

Answer to Problem 8STP

Correct answer :

The correct answer is option (B) 3.

Explanation of Solution

Explanation/justification for the correct answer :

Option (B) 3. The individual organisms in which there are three chromosome sets are called triploid (3n). Each gene in the cells have three alleles. Thus, this is the correct answer.

The explanation for the incorrect answer :

Option (A) 1.The individual organisms in which there are three chromosome sets are called triploid (3n). Each gene in the cells have three alleles. Thus, this is an incorrect option.

Option (C)6. The individual organisms in which there are 6 chromosome sets are called hexaploid (6n). Each gene in the cells have six alleles. Thus, this is an incorrect answer.

Option (D) 9. The individual organisms in which there are nine chromosome sets (9n). Thus, this is an incorrect answer.
