Finally, we note that the present situation does not reflect any situation observed in human genetics. However, these analyses are appropriate for plant and animal genetics. In particular, homozygous inbred strains and their F1 hybrids offer investigators the ability to observe the characteristics of hundreds of genetically identical organisms in a variety of contexts. Furthermore, the analyses of monozygotic twin data and longitudinal phenotype data are also amenable to analysis with generalized linear models.
