most common in the US
Produce too much mucus in the body
recessive gene
homozygous recessive
Genetic

| Huntington's Disease | Lethal
Genetic
Dominant gene
motor neurons are being destroyed, usually notice by age 35 which the genes have already been passed down by then.

Recessive allele, cannot differentiate between green&blue, red&yellow
🗑
|
||||
| Polygenic | Dependent upon alleles in two or more gene pairs
🗑

🗑
|
||||
| Chromosomal Nondisjunction | a chromosome fails to separate from its homologous during meiosis (3 instead of 2 chromosome)
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
