1. Patterns of Heredity Review

2. What mode of inheritance shows a blending of a trait? – Incomplete dominance

3. What did Gregor Mendel use to conduct his experiment? – Garden peas

4. Anything that can cause a mutation? – Mutagen

5. Inheritance where more then ONE gene controlling a trait – Polygenetic inheritance

6. Abnormal number of chromosomes – Aneuploidy

7. Body chromosomes; pairs 1- 22 – Autosomes

8. Failure of the homologous chromosomes to separate during meiosis – Nondisjunction

9. A chart where the chromosomes are arranged in their homologous pairs – Karyotype

10. An individual with the genotype Ai for their blood type would have what blood type? – A blood type

11. Mutation that occurs when a segment of a chromosome breaks off and is reinserted backwards – Inversion

12. Error in DNA that adds of deletes a single base that causes all the following amino acids to be affected – Frame shift mutation

13. The normal karyotype of a human male would be… – 46, XY

14. Give an example of a genotype that would represent a carrier –XMXm–XMXm

15. When a chromosome breaks off & joins another chromosome, this mutation is called – Translocation

16. What type of inheritance has phenotypes of heterozygous offspring showing BOTH traits? – Codominance

17. What type of inheritance is shown when the trait occurs more frequently in one sex than another? – Sex-linked trait

18. What type of inheritance is exhibited when there are more than 2 possible alleles for a certain trait or phenotype? – Multiple alleles

19. A mother who is heterozygous for type A blood marries a man who is homozygous for B blood. What are the blood type of the children? – 50 % - B blood type – 50% - AB blood type

20. In pedigrees, how are males and females represented? – Males – squares – Females - circles

21. What do the roman numerals represent that are labeled on a pedigree? – Generation numbers
