1. Identify the process being illustrated?

2. If a boy inherits a recessive allele from his mother, which of his sex determining chromosomes would it be on?

3. What is a mutation?

4. In pigeons, there is a rare inherited condition that causes death before hatching. In order to be passed on what must the parents be?

5. It is possible for someone to be carrying a lethal allele but be unaffected by it. How is this

possible?

6. True of FalseMutations are ALWAYS harmful and

deadly.

7. What type of cell must a mutation occur in to be able to pass

it on to offspring?

8. What type of chromosome mutation is this?

9. Is this karyotype normal or does it have a genetic disorder?

10. How many generations are represented by the pedigree?

11. Identify the genotypes for the following blood types

A blood

B blood

AB blood

O blood

12. What disease would people who receive excessive radiation to

their body cells be called?

13. Would THIS be something passed on to future generations?

14. Excess mucus production is characteristic of what genetic

disorder?

15. Abnormally shaped blood cells is characteristic of what genetic

disorder?

16. Developmental delays and having been born at home would be characteristic of what genetic

disorder?

Answers1. Crossing over2. X chromosome3. Any mutation in DNA4. Heterozygous

5. The lethal allele is recessive and they have one dominant normal allele. Meaning they are heterozygous

6. False, some can cause genetic diversity that doesn’t lead to death, but new species or variations among animals

7. A sex cell(gamete)

8. Inversion

9. Normal

10. 411. AA or AO, BB or BO AB OO12. Cancer13. No, body cells are not passed to offspring, only sex cells14. Cystic fibrosis15. Sickle cell16. PKU
