Question

Determine which is the result of complementation or which fails to complement in terms of gene interaction. The two options for answers are as follows: a) complementation or b) not complement Please spell the answers and report in all lowercase correctly to receive full points. Thus, the answer to the question shall either be "complementation" or "not complement".

Questions for determination:

3) Null mutation Blank 3

4) Recessive mutation Blank 4

5) Alleles of the same gene Blank 5

6) Alleles of different genes Blank 6

Answer 1

Determine which is the result of complementation or which fails to complement in terms of gene interaction. The two options for answers are as follows: a) complementation or b) not complement  

Questions for determination:

1) Wild type progeny: complementation (Explanation: obtaining wild type progeny from homozygous recessive strains is a result of complementation.

2) Not wild type progeny: not complement (Explanation: in the case of non complementation two mutations together result in a mutant phenotype)

3) Null mutation: not complement (Explanation: in null mutation, there is complete loss of a function of gene)

4) Recessive mutation: complementation (Explanation: complementation test will work when both mutations are recessive)

5) Alleles of the same gene: not complement (Explanation: If recessive mutations represent alleles of the same gene, then they will not complement)

6) Alleles of different genes: complementation (Explanation: When each mutant carries a functional version of the other gene and two mutations are alleles of different gene, then the double heterozygote exhibits a wild-type phenotype due to complementation)
