Term
| Why is reproduction important? |
|
Definition
Organisms produce
offspring through the process of reproduction. Reproduction is
important to all living things. Without reproduction, species
could not continue. |

Term
| Why is it likely that you look like your parents? |
|
Definition
| Heredity is the passing of traits from parents to offspring. You would look like your parents because you inherited that trait from your parents. |

|
Term
| What are the differences between pure and hybrid genes? |
|
Definition
| If a pair of chromosomes contains different alleles for a trait, its hybrid, when a trait has two identical alleles, its pure. |
|
|
Term
| Why are two recessive alleles needed for a recessive trait to be shown? |
|
Definition
| Two recessive is needed or else the dominant would take over. |

Term
| What functions of cells can be affected by a mutation? |
|
Definition
Sometimes mutations
affect the way cells grow, repair, and maintain themselves. This
type of mutation is usually harmful to the organism. Many
mutations, such as a four-leaf clover, have a neutral effect.
Whether a mutation is beneficial, harmful, or neutral, all mutations
add variation to the genes of a species. |
