Mothers who consume excessive alcohol during pregnancy may have babies who are affected with a pattern of physical and mental disabilities known as fetal alcohol syndrome. Similarly, mothers who become addicted to drugs during pregnancy may have babies who show signs of addiction. Do these examples contradict the statement that traits acquired by the parents are not transmitted to the offspring?
For a trait such as flower color in snapdragons that is determined by two alleles with incomplete dominance, the offspring of true-breeding parents show an intermediate phenotype. This is also what would be expected of blending inheritance. The difference is that the trait with:
A)Mendelian inheritance will lose the variation over time. B)blending inheritance will lose the variation over time. C)Mendelian inheritance shows no segregation in the F2 generation. D)blending inheritance shows segregation in the F2 generation.
