Question

Genes a, b, and c are linked on one autosome. In a series of two point mapping crosses, the following genetic distances were determined. What is the sequence of the three genes? a) abc b) bac c) acb Question 18 refers to the genetic map shown below: If a strain heterozygous at loci g, h and k were used in a three point mapping experiment, of 1,000 offspring one would expect _____ double-crossover individuals. a) 2 b) 10 c) 20 d) 200 e) 30 Genes A and B are 5 map units apart. A doubly heterozygous female and a homozygous recessive male are crossed. Of two thousand offspring, how many recombinant offspring would be produced? a) 100 b) 10 c) 5 d) 500 e) 50

Explanation / Answer

1. c. acb: a-------10 mu-----c-----------------------------30

3. Answer is A.

5 mu = 5% recombination.

5% = no. Of Recombinants x 100 / Total progeny

5 = ? X100 / 2000

5 x 2000 / 100 = ?

? = 10000/100

? = 100 = Recombinant Individuals
