Question

Chapter 17, Problem 1TY

Summary Introduction

Introduction: The parental and the recombinant type of offspring are produced by linkage and crossing over. The crossing over takes place during the process of egg formation in the F₁ generation. Two of the four egg cells which are produced by meiosis have recombinant chromosomes because of crossing over.

Expert Solution & Answer

Answer to Problem 1TY

Correct answer: The presence of genes on the same chromosome depicts that they are linked. Hence, the correct answer is option d.

Explanation of Solution

Reason for correct answer:

The occurrence of the genes that are linked to each other takes place on the same chromosomes as they do not undergo independent assortment. The linked genes are present together during the process of meiosis. The genes which are not linked together are assorted independently but the linked genes are not. The linked genes which are present on the same chromosome are transmitted together as a unit.

Option d. is given as “linked”.

Linked genes appear together on the same chromosome. Hence, the correct answer is option d.

Reasons for incorrect answer:

Option a. is given as, “homologous”.

Chromosomes having similar genetic material with little variations are known as homologous chromosomes. The two genes which appear on the same chromosome are not known as homologous genes. Hence, option a. is incorrect.

Option b. is given as, “allelic”.

The two different versions of the same gene present on the homologous chromosomes are known as allelic genes. Allelic genes are not two genes present on the same chromosome. Hence, option b. is incorrect.

Option c. is given as, “epistatic”.

Gene that masks the phenotypic effect of another gene is known as the epistatic gene. Thus, epistatic genes are not two genes that are present on a single chromosome. Hence, option c. is incorrect.

Option e. is given as, “polygenic”.

When the outcome of a particular trait is affected by various genes it is known as polygenic inheritance. Thus, polygenic genes are not the genes that occur on the same chromosome. Hence, option e. is incorrect.

Hence, the options a., b., c., and e. are incorrect.

Conclusion

Thus, the linkage is a phenomenon that depicts the presence of two genes linked together on the same chromosome.
