Life Genetics #2
| Question | Answer |
|---|---|
| The study of how traits are passed from parents to offspring, from one generation to the next | genetics |
| The passing of traits from parents to offspring | heredity |
| A distinguishing quality that all members of a species have in common | trait |
| Many different forms of the same trait in general. (such as brown hair, blonde hair, black hair or red hair) | variations |
| Male and female reproductive cells (sperm and egg) | gametes |
| A small segment of DNA that carries hereditary information, and determine an organism's traits | gene |
| When the egg of one individual is fertilized by the pollen (sperm) of another individual | cross-fertilization |
| The offspring produced by cross-fertilization | hybrid |
| Two different forms of the same gene in your DNA, of which the dominant one will be the observable trait. (In Bb, the dominant one is the capital B) | alleles |
| The characteristic that shows up and masks the recessive trait | dominant trait |
| A characteristic that disappears, and is only physically present when there are two alleles of that trait | recessive trait |
| The combination of an organism's dominant and recessive alleles for a trait | genotype |
| The observable traits of an organism | phenotype |
| An offspring that has different alleles from each parent for a particular gene (Bb) | heterozygous |
| An offspring that has the same allele from both parents for a particular gene (BB or bb) | homozygous |
| The set of chemical instructions that cells use to translate the genetic information from DNA | genetic code |
| The type of asexual reproduction in which new individuals split off from existing ones | budding |
| The type of asexual reproduction in which each spore can grow into an adult | spores |
| The type of asexual reproduction in which a strand of genetic material is copied, dividing into two new identical cells | binary fission |
| The type of asexual reproduction in which a cutting develops roots, and grows into a new plant | vegetative propagation |
