Mendel’s Laws of Inheritance
Name____________________________________________________ Date_____________ Period___________
List the three laws and define them in your own words.
1. Law of Dominance-
2.
Law of Segregation-
3. Law of Independent Assortment-
For the following statements determine which Law of Inheritance is being described. Explain your thinking.
4. Which of Mendel’s four hypotheses can, on its own, directly explain why
there are NO white flowers in the F1 generation and why the purple F1’s
look just as purple as the purple P’s?
5. Offspring acquire one factor from each parent.
6. The principle stating that one factor in a pair of traits dominates the other in inheritance unless
the factors in the pair are recessive.
7. Half of the progeny inherit one allele and half of the progeny inherit the other allele
8. When hybrids for a certain characteristic are crossed (Aa × Aa) the recessive genotype (aa) may appear in some
of the offspring because of
9. Use the picture to
determine the law. Focus
on the cells before they
divide.
10. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype.
11. Which genetic principle is best illustrated by the phenotype of the offspring the
figure to the right?
12. George has a genotype of GgHH and can make the following gametes: GH and
gH. All possible combinations of factors can occur in the gametes.
13. Use the following diagram to determine the law associated with it.
the principle stating that the laws of chancegovern which particular characteristics of the parental pairs will occur in eac
h individualoffspring.
