Term
| What were Mendel's three key choices that made his experiment successful? |
|
Definition
1. Control over breeding
2. Use of purebred plants
3. Observations of either-or traits that appeared in only two alternate forms |
|
|
Term
| What does Mendel's Law of Segregation state? |
|
Definition
1. Organisms inherit two copies of each gene, one from each parent
2. Organisms donate only one copy of each gene in their gametes. Two copies of each gene separate during gamete formation |

|
Term
| How are the terms gene, locus, and allele related? |
|
Definition
| A gene has a specific locus (location) on a chromosome where it can be expressed in alternative forms called alleles. |
|
|
Term
| True or False: A plants with the genotype of Pp is heterozygous recessive |
|
Definition
| False; A gentotype can never be heterozygous recessive only heterozygous dominant |
|
|
Term
| From and PP x Pp cross, what percentage of the the flowers would have purple flowers? |
|
Definition
|
|
Term
| If you have a purple flower but you don't know its genotype, what should you breed with it so that you can quickly find out its genotype? |
|
Definition
| A homozygous recessive white flower |
|
|
Term

Definition
| You can do this one one your own. Too lazy to show the answers. |

Definition
| First, doctors take a drop of blood from the baby's heel at around day 2 and place them on filter paper. If bacteria grows on blood sample, then an excess of phenylalamime is present. If no bacteria gorwth is shown, then there is a balanced amount of phenylalanine. |

Term
| Name four autosomal recessive genetic disorders mentioned in Chance's Choices and the Human Genetics Problems. |
|
Definition
| PKU, B-Thalessemia, cystic fibrosis, and alibinism |
|
|
Term
| Name two autosomal dominant genetic disorders discussed in Chances Choices and the Human Genetics Problems. |

|
Definition
|
|
Term
A x B = AB
What type of inheritance would this be? |
|
Definition
|
|
Term

|
Term
| Which disorder causes the death of nerve cells in the brain? |
|
Definition
|
|
Term
| What are some of the disorders that cause retardation? |
|
Definition
| Fragile X syndrome, Down syndrome, PKU |
|
|
Term
| Which disorders are treated with dietary plans? |
|
Definition
| PKU, FH, Huntington's disease |
|
|
Term
| Why would disorders caused by a dominant allele be more common than disorders caused by a recessice allele? |
|
Definition
| Because in autosomal dominant disorders, a person only need one allele for the disorder to show, while in autosomal recessive disorders, a person needs two alleles for the disorder to show. |
