A cat that lost its tail will produce offspring with shorter tails. A scientist has observed animals in a particular habitat for some time. In a population, genetic typing reveals the genotypic distribution to be 50 GG, 30 Gg, and 20 gg. Individuals with different genotypes may pass on their traits at different rates to the next generation.
