Document Summary

Sliding scale for any range of phenotypes for instance diseases. Some diseases have strong, simple genetic basis, no major role for environment. heart disease and diabetes genetic and environmental component. Important for mendel to look at simple traits to understand inheritance. Agriculture cattle and crops with favourable traits chosen to breed. These questions had no answers until mendel"s paper. Rapid generation time so can look at generations; maturation time from baby to adult in short span of time. Look the same every generation highly homozygous in these lines. Also important that peas/models have discrete options for traits. Long v. short stems discrete type of inheritance. Dominance all of plants were one phenotype. In f1 generation, trait present is called dominant; missing trait is recessive. Green, recessive, appeared in next generation no mixing of the two colours, into an intermediate colour that persisted into the next generations. Basic idea that adult plant that makes yellow seeds.
