Question

The relative location of four genes on a chromosome can be mapped from the following data on crossover frequencies Genes B and D Frequency of Crossover 5% Cand A 15% A and B 30% C and B 45% Cand D 50% Which of the following represents the relative positions of these four genes on the chromosome? 1. ABCD 2. ADCB 3. CABD 4. CBAD

Answer 1

Answer:

The relative position of the genes on the chromosome is CABD  

Explanation:

According to the observed recombination events, C and D are the furthest from each other, while C is closest to A, being therefore CABD the correct gene order in the chromosome
