Inheriting Genes
| Question | Answer |
|---|---|
| Asexual reproduction | the process by which one organism produces offspring that are genetically identical to it and to each other |
| Sexual reproduction | the process by which female and male sex cells from two parent organisms combine genetic information to produce offspring. |
| Genetic variation | the different combinations of alleles of genes found in a species |
| Random | an event that happens in which the outcome cannot be predicted before it occurs |
| Probability | -the chance that a specific outcome will occur each time an event happens |
| Dominant allele | an allele that is expressed even if only one copy is present |
| Recessive allele | an allele that is expressed only when two copies are present |
| Punnett square | a diagram that shows the potential allele combinations an offspring could inherit from its parents |
| Each parent provides ______________ of the chromosomes to their offspring. (Some, all, or one half) | one half |
| These two sex cells combine to make offspring. | sperm and egg |
| Discovered inheritance using pea plants and figured out dominant/recessive genes. | Gregor Mendel |
| Offspring from sexual reproduction are all (same or different) | different |
| Offspring from asexual reproduction are all (same or different) | same |
