B) lethal alleles
C) semilethal alleles
D) nonessential genes
E) conditional lethal alleles

Question

Quizplus · Accepted Answer

Temperature-sensitive alleles that kill an organism only in a particular temperature range are known as conditional lethal alleles. This is because they cause lethality only under certain conditions (in this case, a specific temperature range), and are otherwise viable. This type of allele is commonly used in genetic studies to investigate gene function, as researchers can manipulate the environmental conditions to control the expression of the conditional lethal allele.
