|---|---|
| Genetics | the study of heredity |
| Fertilization | |
| Trait | specific characteristics of an individual |
| True breeding | same as homozygus |
| Hybrid | offspring from parents with different traits |
| segregation | separation of alleles during gamete formation |
| Independent assortment | genes for different traits can segregate independently during the formation of gametes |
| Gametes | sex cell |
| Homozygous | a gene that has identical alleles |
| Heterozygous | gene with two different alleles |
| phenotype | physical characteristics of an organism |
| genotype | genetic make up of an organism |
| dominant | the allele that shows up |
| Recessive | the allele that hides |
| allele | one of a many different forms of a gene |
| incomplete dominance | when one allele is not completely dominant over another allele |
| codominance | phenotype from both alleles are completely expressed |
| punnett square | diagram used to predict geno and phenotype combinations |
| multiple allele trait | gene with more than two alleles |
