Patterns of Heredity and Human Genetics

2. pedigree
A graphic representation of genetic inheritance, a
diagram made up of symbols

3. trait
Any characteristic that is inherited

4. heterozygous carrier
When an individual Heterozygous individual,
Carries recessive allele

5. cystic fibrosis
Results in the formation and accumulation of
thick mucus in the lungs and digestive tract

6. Tay-Sachs Disease
Lacking enzyme that breaks down lipid in central
nervous system = accumulation of lipid

7. Phenylketonuria
Lacking enzyme that which converts aa
phenylalanine to aa tyrosine =
accumulation of PHE

8. Dominant Recessive
trait trait
Results from one Results from one
dominant allele allele from BOTH
from EITHER parents
parent Example: b
Example: B

9. fetus
A developing
baby

10. cleft chin trait
Simple dominant trait, indentation of chin

11. widow’s peak hairline trait
