Chapter 13: Q. 5 (page 343)

The first suggestion that chromosomes may physically exchange segments came from the microscopic identification of ________.

a. synapsis

b. sister chromatids

c. chiasmata

d. alleles

Short Answer

Expert verified

The correct option is C.

Step by step solution

01

Step. 1 Introduction

The creation of chiasma allows for the interchange of genetic information across non-sister chromatids of homologous pairs. Consequently, chiasma seems to be a mechanism for trait recombination and therefore variability in multicellular organisms.

02

Step. 2 Explanation for correct option.

Chiasmata seem to be X-shaped forms created throughout meiosis as a result of the point of contact among coupled chromatids.

03

Step. 3 Explanation for incorrect option.

Option a. During early meiosis, synapsis occurs, which is the grouping of sister chromatids, one per parent.

Option b. Sister chromatids are duplicates of one another generated through Replication of dna.

Option d. Alleles are one among two or even more DNA sequences found at a specific gene locus.
