question 227

Short Answer

Refer to the table.In mice, a single-gene mutation can lead to obesity.The Ob gene codes for the protein leptin.The recessive ob allele is a loss-of-function allele, so ob/ob mice do not produce leptin.In an experiment, leptin was injected into ob/ob and Ob/Ob (wild-type) mice daily.The data in the table below were collected before the injections began (baseline) and 10 days later.(Assume that the Ob allele is dominant.) What baseline values would you expect from mice with the heterozygous genotype Ob/ob?
