Question

You have two fly lines carrying two different alleles of white, called wco (coral) and wch (cherry). Coral and cherry are in the same complementation group and exhibit NO complementation. Which is true regarding recombination between these alleles in a cross:
a. recombination is never observed because coral and cherry are in the same complementation group
b. recombination is impossible because they are in the same gene (white)
c. recombination is never observed because coral and cherry display the same phenotype
d. recombination is possible and can generate a wild-type allele and a double mutant allele

Answer 1

Answer:

Recombination is possible and can generate a wild-type allele and a double mutant allele ( D )

Explanation:

The true statement regarding the recombination between the alleles is : Recombination is possible and can generate a wild-type allele and a double mutant allele.

The recombination process involves the breaking and recombination of pieces of DNA in order to produce new alleles. this recombination ( crossover ) results to the offspring possessing different combination of genes ( wild -type allele and double mutant allele ).  hence option D is the correct answer.
