Why are conditional alleles useful in studying genes with functions in essential cell processes?

Conditional genes enable to study the gene function by manipulating the gene of interest

Explanation:

Conditional alleles are widely used in molecular genetics to study gene function in target tissues or developmental stages. A conditional allele can be produced by introducing two recombinase recognition sites (SRSs) at flanking regions of the target gene, thereby deletion/inversion of these sites induced by a specific recombinase will produce a null allele. Generally, conditional alleles are designed by introducing LoxP sites flanking the gene of interest; however, classical gene targeting methods (i.e., by homologous recombination) have been historically used in order to produce conditional alleles.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.

explanation:

sex cells are usually half's then they find another half and make a fertilize egg
