In rats, the allele for long whiskers is dominant to the allele for short whiskers. at another gene locus, a dominant allele produces whiskers and the recessive allele produces a rat with no whiskers. the alleles at these 2 gene loci assort independently. if a rat that is homozygous for both recessive alleles is crossed with a rat that is heterozygous at both gene loci, what percentage of the offspring are expected to have short whiskers? ( enter the number only without the percent sign. for example, enter 100% as 100 and enter 12.5% as 12.5 )
