|---|---|---|---|---|---|
| Heterozygous (hybrid) | has both dominant and recessive allele. ALWAYS has DOMINATE phenotype.
🗑
|
||||
| homozygous (purebred) | same alleles (dominant or recessive). ex. RR or rr
🗑
|
||||
| dominant allele | capital (big) allele represents dominant trait.
🗑
|
||||
| recessive allele | lowercase (small) allele represents recessive trait. hides if dominant allele is present.
🗑
|
||||
| Base pair rules of DNA sequencing | Cytosine (c) goes with Guanine (g). Adenine (a) goes with Thymine (T).
🗑
|
||||
| Base pair rules of RNA | Cytosine (c) goes with Guanine (g). Adenine (a) goes with Uracil (u). NO THYMINE!
🗑
|
||||
| What controls the production of proteins? | genes control the production of proteins.
🗑
|
||||
| genotypes | letter combination of the alleles. for example, BB, Bb, or bb
🗑
|
||||
| phenotypes | the form of the trait that an organism displays or looks like. for example, tall or short, purple or white, smooth or wrinkled.
🗑
|
||||
| shape of DNA molecule | double helix
🗑
|
||||
| punnet square | a tool used to show all the possible gene combinations from both parents.
🗑

| How many alleles do each sex cells give? | 1 (from both female and male)
🗑
|

| What is the study of genetics? | Heredity
🗑
|
||||
| Which pair of chromosomes make a male offspring? | xy
🗑
|
||||
| Which parent's genes decides if a human baby will be boy or girl? | Father because he can give xy. Mother can only give xx.

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.
