Question

Which phenotype of the mutants above would the expression of lin-4 during the first larval stage of development share.

A. Wild-type
B. lin-14lf/lin-14lf
C. lin-14gf/+
D. lin-4lf/lin4lf
E. lin-14lf/+
F. lin-4lf/+

Answer 1

The phenotype that would share the expression of lin-4 during the first larval stage of development is lin-14lf/+.

Step-by-step explanation:

The phenotype of the mutants above that would share the expression of lin-4 during the first larval stage of development is E. lin-14lf/+.

lin-4 is a microRNA that regulates the expression of lin-14, a gene involved in controlling developmental timing in Caenorhabditis elegans. The lin-14lf mutation leads to constitutive expression of lin-14, while the lin-14gf mutation reduces its expression. In the lin-14lf/+ genotype, one copy of lin-14 is constitutively expressed and the other copy is under normal regulation by lin-4. This results in a phenotype similar to wild-type.

Therefore, the expression of lin-4 during the first larval stage would be shared with the lin-14lf/+ phenotype.
