BbEe mice were intercrossed to produce homozygous-deficient mice for both genes (bbee). All allele frequencies were in a manner following Mendelian law.
Light sensing is a critical function in most organisms and is mediated by photoreceptor proteins and phototransduction. Although most nematodes lack eyes, some species exhibit phototaxis. In the nemat
Data shown are the number of mice of a given genotype (percentage of total progeny). Chi square analysis determined that there was no significant difference from expected ratios.
