What is Lethal Genes and Gene Interactions about?

- Multiple alleles occur at the same locus and control the same trait but with varying effects. Examples include wing size alleles in Drosophila. - Pleiotropic genes have multiple effects and influence multiple phenotypic traits. - Lethal genes are recessive and cause death in the homozygous state. Examples include genes for sickle-cell anemia and Tay-Sachs disease. - Gene interactions include incomplete dominance where heterozygotes exhibit an intermediate phenotype between the homozygotes.
