| traits | all the features that an organism inherits
🗑
|
||||
| gene | part of DNA code on a chromosome
🗑
|
||||
| chromosome | carries genes that determine heredity. (found in the nucleus)
🗑
|
||||
| genotype | genetic makeup
🗑
|
||||
| phenotype | traits you see when you look at an organism
🗑
|
||||
| allele | different form of genes
🗑
|
||||
| homozygous | alleles that are the same for a trait
🗑
|
||||
| heterozygous | alleles that are different for a trait
🗑
|
||||
| Dominant Alleles | trait that will always show up when in the genotype.
(Capital letters are used to show dominant traits)

It could take several generations before traits show up.
Examples: dairy cows, cotton seeds, vegetables, horses, dogs, etc...
🗑
|
||||
| Genetic engineering | biological and chemical methods to change the arrangement of DNA that make up genes or plants and animals
🗑
|
||||
| Reasons AGAINST selective breeding and genetic engineering... | 1. Changing one gene may negatively affect other genes.
2. Long term health effects are not known.
3. May harm natural world.
4. New kinds of crops may create new kinds of poisons and allergies.
