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 |
