This visualization displays the distribution of weight and fat-to-lean mass ratio across mice with different Nnat gene modifications on three background strains: C57BL/6 (B6), 129, and A/J. The genotypes include wild-type mice (B6, 129, A/J), heterozygous Nnat mutants (B6.Nnat+/-, 129.Nnat+/-, AJ.Nnat+/-), homozygous Nnat mutants (B6.Nnat+/+, 129.Nnat+/+, AJ.Nnat+/+), and hybrid mice (129xB6).
