View Available Hint(s) Mendel's unit factors in pairs are most accurately known to be _______. two alleles on nonhomologous chromosomes two maternal chromatids Identical alleles on homologous chromosomes two alleles on paternal and maternal homologs

Answer 1

two alleles on paternal and maternal homologs

Step-by-step explanation:

Mendel didn't know about the existence of genes, the units of heredity. However, from his experiments, Mendel realized that cells contain some type of "two-state factor" capable of controlling the inheritance pattern for each of the traits he examined. Mendel hypothesized that these factors might be inherited in the offspring to form three possible combinations: AA, Aa, and aa, where 'A' represents the dominant factor, while 'a' represents the recessive factor. Nowadays, it is well known that Mendel's factors are two gene variants (i.e. alleles), one inherited from the mother and the other inherited from the father.
