How many babies does a gerbil have in year?

A gerbil can have multiple litters in a year, with each litter consisting of an average of 4 to 8 pups. The gestation period for gerbils is approximately 24 to 26 days, and the female gerbil can become pregnant again shortly after giving birth. Given these factors, a gerbil could potentially have several litters in a single year, depending on the breeding conditions.
