Heredity

an allele that is masked when a dominant allele is present

the set of information that controls a trait

an allele whose trait always shows up in the organism when the allele is present

when characteristics are passed from parent to offspring

the scientific study of heredity

the children of an organism

having two different alleles for a trait

having two identical alleles for a trait

having 2 different alleles for a trait

a dog breeder mating 2 dogs to make more dogs

a farmer grows bees to pollinate the plants on his farm

a person pollinates 2 white rose plants to only create white roses

a process to create an organism with desired traits from parents with those desired traits

natural method of producing offspring with desired traits

creating a new species

making organisms reproduce during times of stress

GMO's can impact the environment, Selective breeding can not

GMO's have been happening for thousands of years, Selective breeding is a new practice

Selective Breeding occurs over several generations, GMO's are produced rapidly in the lab

Selective breeding occurs in only plants. Both plants and animals can be genetically modified

Pest & Disease resistance

Improved Nutrition

Ability to survive in stressful conditions (ex. Drought)

Lower crop yield and size
