Question

Which recombination frequency corresponds to independent assortment and the absence of linkage?

a. 0

b. 0.25

c. 0.50

d. 0.75

Short answer

The Correct answer is C.

Step-by-step solution

Step. 1 Introduction

Independent Assortment illustrates how various genes individually segregate of each other throughout the development of genetic material.

The strong relationship between alleles or any other Nucleotide sequences on the very same chromosomes is referred to as linkage.

Step. 2 Explanation for correct answer.

According to the rules of independent assortment, alleles for a variable split whenever gametes develop and thus are randomly joined throughout the fertilisation process. During meiosis, the parents' pairs of homologous chromosomes are split in half and donated during fertilisation to form the reproductive cells, which at the commencement of meiosis will randomly couple up the alleles, leading in recombination of DNA distinct from both parents. The frequency of recombination always seems to be less than 50%.

Step. 3 Explanation for incorrect answer.

Option a. 0% means that the alleles are indeed very near to one other, resulting in a complete linkage.

Option b. 0.25 indicates just gene recombination.

Option d. 0.75 is not attainable because it does not confirm the lack of linkage.
