Question

while mapping two genes in drosophila, you observe 30 recombinants among 200 total offspring. what is the distance between these genes? multiple choice 200 map units 6.67 map units 15 map units 30 map units

Explanation:

Step1: Recall the formula for genetic - map distance

Genetic - map distance = (Number of recombinants / Total number of offspring)×100

Step2: Substitute the given values

Number of recombinants = 30, Total number of offspring = 200. So, Genetic - map distance=$\frac{30}{200}\times100$

Step3: Calculate the result

$\frac{30}{200}\times100 = 15$

Answer:

C. 15 map units
