Explain the circumstances that led to a debate about whether all inheritance cases could be explained by Mendelian inheritance or whether there might be another, separate mechanism of inheritance that did not follow the laws of segregation and independent assortment. Summarize the outcome of that debate
What will be an ideal response?
Geneticists turned up cases in which the F1 phenotypes were not identical to one of the parents. In some cases, the offspring had a phenotype intermediate to that of the parents or a phenotype in which the traits of both parents were expressed. Eventually, research showed that although phenotypes can be somewhat complex, these cases were not exceptions to Mendelian inheritance at the level of genotypes. Although phenotypes may not follow predicted ratios, genotypes do obey the principles of Mendelian inheritance.
